Summary
Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.14.0 through 4.14.6, a low-privilege API user can read the cleartext cluster key from a configuration endpoint that fails to redact it. The REST API provides a masking control, mask_sensitive_config, that redacts sensitive fields such as authd.pass and cluster.key from configuration responses for users who lack update-config permission, and every config-read endpoint carries this decorator except GET /cluster/local/config. That endpoint, backed by read_config_wrapper, is gated only by cluster:read and returns the local node's cluster configuration including the cleartext key, whereas its siblings return the same value masked. As a result, any account with the default readonly or cluster_readonly role, which is explicitly denied update-config precisely so it cannot view secrets, receives the real cluster key. Because the cluster key authenticates and encrypts traffic between cluster nodes, disclosing it to an unprivileged account provides the authentication precondition for the cluster-peer remote code execution chains established by prior advisories. This issue is fixed in version 4.14.

- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.4.0 through 4.14.6, a party holding the cluster key can write, overwrite, or delete arbitrary files under /var/ossec on worker nodes, leading to remote code execution as root. During cluster file synchronization, the non-merged branch of update_master_files_in_worker() moves each staged file to a destination derived only from safe_join(), which confines the path to /var/ossec but never verifies that the file lands in the directory declared by its cluster_item_key. Because the destination check present on the primary node and on the worker's merged branch was not applied, a peer can place files at attacker-chosen locations under /var/ossec, including paths that are executed as root, and the delete branch has the same gap. This is an incomplete fix for CVE-2026-30893, which addressed traversal outside /var/ossec but left this path able to redirect files anywhere within it. This issue is fixed in version 4.14.7.

Summary
Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.14.0 through 4.14.6, an authenticated low-privilege user can read the cluster secret from the manager configuration because the logic that masks sensitive values is disabled by any update-config RBAC rule, including an explicit deny. The mask_sensitive_config() decorator applies masking only when _has_update_permissions() returns false, but that gate treats a user as able to update the config whenever a manager:update_config or cluster:update_config rule exists, without ever checking whether the rule's effect is allow or deny. Because a deny rule is stored as a real entry, a read-only account that is hardened by explicitly denying config edits is counted as having update permission, which turns masking off. A single authenticated GET request to the configuration endpoint with raw=true then returns the verbatim ossec.conf XML with cluster.key in clear, whereas an otherwise identical account without the deny rule sees the value masked. This issue is fixed in version 4.14.7.

CWE
- CWE-476 - NULL Pointer Dereference
Summary
Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.0.0 through 4.14.6, a malicious or man-in-the-middle enrollment manager can crash a Wazuh agent during enrollment by returning a malformed key response with fewer than four fields, causing a NULL pointer dereference. The w_enrollment_process_agent_key() routine splits the manager-provided key into four space-separated fields but does not verify that all fields are present before passing them to validators. Because OS_StrBreak() leaves missing trailing entries as NULL and OS_IsValidName() calls strlen() on its argument without a NULL check, a response such as OSSEC K:'1' reaches OS_IsValidName(NULL) and terminates the agent process. Since Wazuh permits enrollment against an unverified manager when no CA certificate is configured, an attacker operating a rogue manager or intercepting the enrollment flow can deterministically crash agents, resulting in denial of service. This issue is fixed in version 4.14.7.

CWE
- CWE-88 - Improper Neutralization of Argument Delimiters in a Command ('Argument Injection')
Summary
Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. In versions 4.2.0 through 4.14.6, multiple active response scripts pass attacker-influenced alert fields to privileged system commands without validating their format, allowing argument injection into tools that run as root. Five of the eight scripts that handle the srcip field, route-null.c, netsh.c, pf.c, npf.c, and ipfw.c, omit the get_ip_version() check that rejects non-IP input, and disable-account.c passes the dstuser field to passwd/chuser with only a comparison against "root". An attacker who can inject crafted log events, for example via syslog, can supply srcip or dstuser values that, when an active response rule triggers, are passed unvalidated to firewall and account-management commands such as pfctl, npfctl, ipfw, route, netsh, and passwd. This enables injecting additional command arguments, and on Windows the unquoted CreateProcess command-line concatenation in wpopenv() lets a srcip containing spaces add further arguments, while disable-account.c can be abused to lock arbitrary system accounts. This issue is fixed in version 4.14.7.

CWE
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Wazuh is an open-source security platform providing unified XDR and SIEM protection for endpoints and cloud workloads. The ip-customblock active response script contains a path traversal vulnerability that lets an attacker create or delete arbitrary files on the filesystem as root. The script builds a file path by concatenating the srcip field taken from alert JSON directly onto the fixed /ipblock/ base directory, without validating that the value is a well-formed IP address. Because the extraction routine returns the raw string unchecked, an attacker who can trigger alert-matching log events with a crafted srcip containing ../ sequences can escape the base directory. The block action opens the resulting path in append mode, creating an empty file at an arbitrary location, while the unblock action passes it to remove(), deleting an arbitrary file; since the active response daemon runs as root, this includes sensitive files such as system credentials and Wazuh configuration. Unlike the sibling scripts host-deny.c, default-firewall-drop.c, and firewalld-drop.c, which reject non-IP input via get_ip_version(), ip-customblock.c omits this validation. This issue is fixed in version 4.14.7.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.6.0 until 4.14.6 and 5.0.0-beta3, DB::getFile() and DB::searchFile() in src/syscheckd/src/db/src/file.cpp concatenate a monitored file path into SQLite row filters. On non-Windows systems, FIMDBCreator::encodeString() does not escape the value. A local user who can create a filename in a File Integrity Monitoring directory can inject a UNION SELECT expression when wazuh-syscheckd processes or deletes that path. The confirmed primitive manipulates SELECT result sets consumed by the FIM code; stacked statements and remote code execution were not demonstrated. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.

- CWE-117 - Improper Output Neutralization for Logs
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.4.0 until 4.14.6 and 5.0.0-beta2, api/api/middlewares.py decodes the Basic authentication username before credential validation and passes it to the access logger without neutralizing control characters. api/api/alogging.py interpolates that value into the plain-text API log. An unauthenticated attacker can include carriage returns or line feeds in the username to forge entries, obscure activity, or poison systems that consume the plain-text audit log. The JSON log format is not affected because JSON serialization escapes these characters. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.5.0 until 4.14.6 and 5.0.0-beta2, compare_wazuh_versions() in src/shared/version_op.c copies the attacker-controlled enrollment V: field into a 10-byte stack buffer with strncpy() but does not explicitly terminate the buffer. The function is reachable before authentication through wazuh-authd on TCP port 1515 when anonymous TLS enrollment is enabled. A version string of at least nine non-null bytes can cause strchr() and strtok() to read beyond ver2 and can make strtok() write a null byte into adjacent stack memory, allowing a remote denial of service. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.3.0 until 4.14.6 and 5.0.0-beta3, the non-merged branch of process_files_from_worker() in framework/wazuh/core/cluster/master.py trusts a peer-controlled file_path key from files_metadata.json. The destination is joined to WAZUH_PATH without proving that it remains inside the directory selected by cluster_item_key. A cluster peer holding the shared Fernet key can upload a crafted extra-valid archive and overwrite security-sensitive files such as /var/ossec/etc/ossec.conf. Replacing ossec.conf can configure root-executed commands and lead to code execution after a service reload. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.9.0 until 4.10.4 and 4.14.6, PUT /security/users/{user_id} in api/api/controllers/security_controller.py passes request.get("user") instead of request.context['token_info']['sub'] as current_user. remove_nones_to_dict() removes the resulting None value, so the reserved-account protection in framework/wazuh/security.py cannot verify who is making the request. An authenticated user with the users_admin role can overwrite the password of protected administrator accounts with user IDs at or below 99, including the wazuh superuser, and gain full administrative control. This issue is fixed in versions 4.10.4 and 4.14.6.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta2, AuthenticationManager.check_user() in framework/wazuh/rbac/orm.py performs check_password_hash() only when the supplied username exists. A nonexistent username returns immediately, while a valid username causes an expensive bcrypt calculation. An unauthenticated remote attacker can compare authentication response times to enumerate valid Wazuh usernames and use that information in subsequent credential attacks. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.

CWE
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta3, cluster.unmerge_info() in framework/wazuh/core/cluster/cluster.py constructs paths from peer-controlled merge_type and name values in a merged synchronization archive. process_files_from_worker() in framework/wazuh/core/cluster/master.py does not adequately confine the resulting path to the declared cluster item directory. A cluster peer holding the shared Fernet key can use traversal in files_metadata.json or a merged-file header to write files such as /var/ossec/etc/ossec.conf. Replacing ossec.conf can configure root-executed commands and lead to code execution when Wazuh services reload. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.

- CWE-73 - External Control of File Name or Path
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta3, DistributedAPI.send_tmp_file() in framework/wazuh/core/cluster/dapi/dapi.py joins an attacker-controlled tmp_file value to WAZUH_PATH without canonicalization or confinement. A cluster peer holding the shared Fernet key can use traversal or an absolute path to make the master return any readable file over the cluster channel. Reading /var/ossec/api/configuration/security/private_key.pem allows the peer to forge administrator REST API tokens offline and then exercise administrative privileges without creating an account. This issue is fixed in versions 4.14.6 and 5.0.0-beta3.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta2, AffectedItemsWazuhResult.merge() in framework/wazuh/core/results.py trusts the sort_casting field in a cluster worker's JSON response. During a distributed API merge, attacker-controlled type names are resolved through Python builtins without an allowlist. A compromised worker can set sort_casting to exec and place Python source in affected_items, causing the master to execute the payload as root when responses from multiple nodes are merged. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.

From 1.0.0 until 4.14.6 and 5.0.0-beta2, HandleSecureMessage() in src/remoted/secure.c passes a pointer inside its stack buffer to ReadSecMSG(), and src/os_crypto/shared/msgs.c decompresses up to OS_MAXSTR bytes at that offset. For an encrypted agent message on TCP port 1514 that expands to 65,536 bytes, os_zlib_uncompress() writes a terminating null byte beyond the end of the destination buffer. The resulting stack out-of-bounds write in the root-level remoted daemon can crash message processing and disrupt agent communications. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.

- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.6 and 5.0.0-beta2, WazuhCommon.end_receiving_file() in framework/wazuh/core/cluster/common.py allows a cluster-authenticated node to delete files outside WAZUH_PATH. A syn_i_w_m_e request with an unknown task_id reaches the cleanup branch, where an attacker-controlled filename is passed to os.path.join without canonicalization or confinement. Absolute paths and traversal sequences can therefore target files such as ossec.conf, jwt_secret.json, TLS certificates, and ruleset files that are accessible to the Wazuh manager process. Deletion can disable the manager, invalidate API tokens, or disrupt cluster and API connectivity. This issue is fixed in versions 4.14.6 and 5.0.0-beta2.

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 3.9.0 until 4.14.5 and 5.0.0-beta2, the Wazuh cluster protocol in framework/wazuh/core/cluster/common.py allows an authenticated cluster node to exhaust memory on the master. The receive_str() method accepts an attacker-controlled total for InBuffer without a maximum, so a new_str command can request a multi-gigabyte bytearray and repeated requests accumulate in in_str. The divided-message path also retains flag_divided fragments under unique counters in div_msg_box without a count, aggregate-size, or expiration limit. Exploitation can disrupt agent connectivity and alert processing across the monitored environment. This issue is fixed in versions 4.14.5 and 5.0.0-beta2.

- CWE-863 - Incorrect Authorization
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. From 4.0.0 until 4.14.5, Wazuh Manager allows a low-privilege read-only API user with manager:read permission to retrieve the cluster key from the element in ossec.conf through GET /manager/configuration?raw=true. An attacker with network access to TCP port 1516 can use the disclosed Fernet key to impersonate a cluster worker and submit distributed API requests containing attacker-controlled rbac_permissions with rbac_mode set to black. Because the master trusts the worker-supplied authorization context, the attacker can create users, assign administrator roles, access credentials and API tokens, modify configuration, and execute actions across agents. This issue is fixed in version 4.14.5.

CWE
- CWE-409 - Improper Handling of Highly Compressed Data (Data Amplification)
Summary
Wazuh 4.4.0 before 4.14.7 contains a denial of service vulnerability in the fdecompress_files() function within cluster.py that allows authenticated cluster peers to exhaust memory by supplying a malicious synchronization archive without decompressed size limits. Attackers holding a valid cluster Fernet key can upload a small, highly compressed zip bomb archive that forces wazuh-clusterd on the master node to decompress the full payload into memory, causing memory exhaustion and service disruption.

CWE
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Wazuh 4.0.0 before 4.14.6 contains a path traversal vulnerability that allows authenticated cluster peers to delete arbitrary directory contents by supplying a traversal-shaped node name in the cluster hello payload without validation. Attackers holding a valid cluster Fernet key can craft a malicious node name and disconnect, triggering the master's peer cleanup routine to remove the contents of arbitrary directories within the Wazuh installation path writable by the wazuh user.

Summary
Wazuh 4.0.0 before 4.14.7 and 5.0.0-beta2 contain a denial of service vulnerability that allows authenticated attackers with allow_run_as enabled to exhaust CPU resources by submitting arbitrarily deeply nested JSON structures to the POST /security/user/authenticate/run_as endpoint. Attackers can repeatedly submit malformed auth_context bodies with unlimited nesting depth to cause the API framework to consume excessive CPU, denying service to all other API consumers.

CWE
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Wazuh 4.0.0 before 4.14.6 contains a path traversal vulnerability that allows unauthenticated remote attackers to cause denial of service by enrolling an agent with a dot-sequence name such as ".." through the enrollment port. Attackers exploit insufficient validation in OS_IsValidName() and unsafe path concatenation in delete_diff() to resolve the traversal to the parent queue directory, causing its subdirectories to be removed and stopping all Wazuh services requiring manual recovery.

CWE
- CWE-345 - Insufficient Verification of Data Authenticity
Summary
Wazuh 5.0.0-beta1 (fixed in 5.0.0-beta3) does not validate or override the cluster_name and cluster_node fields in inventory-sync Start FlatBuffer messages, while validating only the agentid against the authenticated agent identity. This allows a low-privileged enrolled agent to spoof cluster attribution in indexed inventory and vulnerability documents by forging wazuh.cluster.name values and influencing the document _id prefix, potentially tampering with inventory records or, in shared-indexer multi-cluster deployments, poisoning another cluster's records when numeric agent IDs collide.

CWE
- CWE-502 - Deserialization of Untrusted Data
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. Prior to version 4.14.5, issues in the Cluster Distributed API (DAPI) handling allow a cluster peer, or any actor able to authenticate to the cluster channel using the shared cluster key, to make the master node deserialize an attacker-controlled callable and execute it under an attacker-controlled RBAC context. The cluster code in `framework/wazuh/core/cluster/common.py` deserializes JSON with `as_wazuh_object()`, which resolves any callable whose top-level package is wazuh or api (an overly broad allowlist controlled only by `ALLOWED_CALLABLES_PACKAGES`), and DAPI requests handled in framework/wazuh/core/cluster/dapi/dapi.py accept a client-supplied rbac_permissions value that `run_local()` applies as the global RBAC context, so supplying an rbac_mode of black causes authorization checks for expose_resources-protected functions to pass without any legitimate permission assignment. Combined, these allow privileged administrative actions on the master node such as arbitrary file writes under WAZUH_PATH, creation of new API users, and tampering with security.yaml, and can be chained into full manager compromise. This issue has been fixed in version 4.14.5.

Combined, these allow privileged administrative actions on the master node such as arbitrary file writes under WAZUH_PATH, creation of new API users, and tampering with security.yaml, and can be chained into full manager compromise. This issue has been fixed in version 4.14.5."

Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.0.0 and above, prior to 4.14.5, a size_t integer underflow in os_crypto/shared/msgs.c:389 allows any enrolled Wazuh agent to crash the wazuh-remoted process on the manager, immediately disconnecting all agents from the manager. A second code path reached by the same underflow may allow heap memory corruption. This issue has been fixed in version 4.14.5.

CWE
- CWE-122 - Heap-based Buffer Overflow
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. Versions 4.6.0 and above prior to 4.14.5 contain a heap-based buffer overflow vulnerability in the syscheck component of the Wazuh agent for Windows. When expanding registry paths containing wildcards (* or ?), the agent allocates a fixed-size heap buffer of 256 bytes (OS_SIZE_256). By creating a registry subkey with a maximum allowed length (255 characters) inside a monitored path, a low-privileged local attacker can force an out-of-bounds write during string concatenation. Since wazuh-agent.exe runs as NT AUTHORITY\SYSTEM, this can lead to a silent Denial of Service (blinding the agent) or potentially Local Privilege Escalation (LPE). This issue has been fixed in version 4.14.5.

CWE
- CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 4.0.0 through 4.10.3 and 4.11.0 through 4.14.4, a logic flaw affects the Wazuh Manager's enrollment daemon (authd) and synchronization daemon (remoted). The authd process allows agents to select a group during enrollment but does not filter path traversal sequences such as "..." While the manager checks for the group directory using wopendir(), the ".." sequence references the parent directory (/var/ossec/etc), allowing it to pass validation. After the malicious group is accepted and stored in the manager's global database, the remoted process uses this unchecked value to build paths for agent configuration synchronization. As a result, sensitive files from /var/ossec/etc, such as client.keys, ossec.conf, and internal certificates, are included in the agent's shared configuration stream and exposed to the attacker. This issue has been fixed in versions 4.10.4 and 4.14.5.

CWE
- CWE-122 - Heap-based Buffer Overflow
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 1.0.0 and above, prior to 4.14.5, a heap buffer overflow in wazuh-analysisd allows an unauthenticated remote attacker to crash the Wazuh manager's analysis engine, causing complete loss of SIEM alert processing. The attack exploits the default configuration shipped in the official wazuh/wazuh-docker deployment with default configuration. An attacker can enroll with authd without a password to obtain a valid agent ID and encryption key, connect to remoted over the Wazuh agent protocol, and inject rootcheck events containing {key: value} patterns longer than 30 bytes that trigger a sprintf overflow of a 30-byte buffer in W_JSON_ParseRootcheck, corrupting the heap and crashing wazuh-analysisd so that all alert processing silently stops while the dashboard and API keep showing stale data.
