- CWE-863 - Incorrect authorization
Summary
A vulnerability has been identified within Rancher where a user with the ability to create a project, on a certain cluster, can create a project with the same name as an existing project in a different cluster. This results in the user gaining access to the other project in the different cluster, resulting in a privilege escalation. This happens because the namespace used on the local cluster to store related resources (PRTBs and secrets) is the name of the project.

CWE
- CWE-250 - Execution with unnecessary privileges
Summary
A vulnerability has been identified within Rancher Manager where the Fleet agent wrote resources to downstream clusters using its own cluster-admin credentials instead of the ServiceAccount pinned to the deployment. It affects multi-tenancy environments where different tenants share the same downstream clusters, for example different privileged or untrusted teams inside the same organization. This could lead to overwritten configuration files.
This issue affected SUSE Rancher Fleet 0.16 before 0.16.2, 0.15 before 0.15.7, and 0.14 before 0.14.11.

CWE
- CWE-266 - Incorrect privilege assignment
Summary
A privilege mismatch was found in Fleet. When a bundle requested namespace labels or annotations through the namespaceLabels and namespaceAnnotations options, the resulting namespace metadata update was not subject to the same authorization as the rest of the bundle's deployment. As a result, a bundle could change labels and annotations on a target namespace even when the identity it was pinned to was not authorized to modify that namespace.
This affected SUSE Rancher Fleet 0.16 before 0.16.2, 0.15 before 0.15.7, 0.14 before 0.14.11, 0.13 before 0.13.16 and potentially older versions.

CWE
- CWE-306 - Missing authentication for critical function
Summary
A vulnerability was discovered in Fleet's Git webhook receiver (the gitjob webhook service). When a webhook secret is not configured, incoming webhook requests are accepted without verification, and processing a request can change the spec.pollingInterval field of a matching GitRepo resource in any namespace. A caller with network access to the webhook service and no Kubernetes credentials can therefore alter GitRepo configuration outside
the namespaces they are authorized for. This only affects SUSE Rancher Fleet 0.16 before 0.16.2, older versions are not affected.

Summary
A cross-tenant authorization issue was discovered in SUSE Rancher Fleet. During agent-initiated cluster registration, cluster labels supplied by the registering agent, including labels in the reserved management.cattle.io/ namespace such as the cluster display name label, were applied to the resulting upstream Cluster object. Because Fleet resolves GitRepo and Bundle targets from those cluster labels, a party able to register a cluster into a Fleet workspace namespace shared with other tenants could cause its own cluster to satisfy targeting rules that administrators intended for a different cluster.
This affects SUSE Rancher Fleet 0.16 before 0.16.1, 0.15 before 0.15.6, 0.14 before 0.14.10, 0.13 before 0.13.15, 0.12 before 0.12.19 and older versions.

CWE
- CWE-23 - Relative path traversal
Summary
A user who can supply bundle content to a repository referenced by a GitRepo resource, for example through Git push access, or through permission to create or modify a GitRepo, can cause SUSE Rancher Fleet to read files from the filesystem of the environment that processes the bundle and include their contents in the generated Bundle resource. This can expose configuration or credential material that the user has no Kubernetes RBAC permission to read, including Helm registry credentials made available to the bundle-processing job when per-path Helm credentials are configured.
This affects Fleet 0.16 before 0.16.2, 0.15 before 0.15.7, 0.14 before 0.14.11, 0.13 before 0.13.16, 0.12 before 0.12.20 and potentially older unsupported versions.

CWE
- CWE-639 - Authorization bypass through User-Controlled key
Summary
A flaw was found in Rancher Manager. When a non-administrative caller supplied a label selector naming a different user, the ext.cattle.io/v1 Token store dropped its internal owner filter instead of returning an empty result. Any authenticated user could therefore list and watch every other user's tokens, disclosing token metadata and the stored salted hash of the bearer token.
This issue affects Rancher: before 2.15.1.

- CWE-294 - Authentication bypass by capture-replay
Summary
A flaw was found in Rancher Manager. The SAML assertion replay protection introduced by the fix for CVE-2026-44946 recorded consumed assertion IDs in a per-process cache, so each replica only detected replays that reached the same pod. In a high-availability deployment, an attacker holding a captured assertion could replay it once against every other replica to obtain additional authenticated sessions as the victim.
This issue affects Rancher: before 2.15.1.

- CWE-639 - Authorization bypass through User-Controlled key
Summary
A flaw was found in Rancher Manager. Project Secrets were propagated into a namespace based only on its `field.cattle.io/projectId` annotation, without verifying that the referenced project belonged to the same downstream cluster. A user able to create namespaces on one cluster could set the annotation to a project ID from another cluster and have that project's secrets copied into a namespace under their control.
This issue affects Rancher: before 2.15.1.

- CWE-639 - Authorization bypass through User-Controlled key
Summary
A flaw was found in Rancher Manager. The GlobalRole controller derived the target ClusterRole name from the user-settable `authz.management.cattle.io/cr-name` annotation and overwrote that object's rules without verifying ownership. A user with delegated GlobalRole create or update permission could point the annotation at any existing ClusterRole, such as `cluster-admin`, and revoke the permissions of every principal bound to it. The change persists after the malicious GlobalRole is deleted.
This issue affects Rancher: before 2.15.1.

- CWE-639 - Authorization bypass through User-Controlled key
Summary
A flaw was found in Rancher Manager. The /v3/users update path did not enforce immutability of a User resource's `username` and `principalIds` fields. A user holding the `update` verb on `users.management.cattle.io` could inject a foreign identity provider principal into any account, so that the next login by the owner of that principal was bound to the victim's account and inherited its role bindings.
This issue affects Rancher: before 2.15.1.

Summary
A privilege escalation vulnerability exists in Rancher's impersonation middleware (pkg/auth/requests/impersonate.go). An authenticated Rancher user with the default user
global role can gain full administrative access to the Rancher control
plane and transitively to all downstream clusters it manages.
This issue affects Rancher: from 2.11.0 before 2.11.16, from 2.12.0 before 2.12.12, from 2.13.0 before 2.13.8, and from 2.14.0 before 2.14.2.

- CWE-204 - Observable response discrepancy
Summary
The endpoint /v3/import/{token}_{clusterId}.yaml retrieves the cluster object before validating the token. When a valid cluster ID references a cluster that has private registry secrets configured, a nil pointer dereference in pkg/systemtemplate/private_registry.go causes the request to return HTTP 502 Bad Gateway. For cluster IDs that do not exist, the endpoint returns HTTP 200. This observable difference in response codes constitutes a reliable enumeration oracle.

CWE
- CWE-770 - Uncontrolled Resource Consumption / Input Handling
Summary
When API audit logging is enabled, the middleware reads the entire HTTP request body into memory without enforcing a size limit on login endpoints. Because the audit middleware is positioned earlier in the handler chain than Rancher's APIBodyLimitingHandler, the body-size cap (default 1 MiB) is bypassed for requests that pass through the audit copyReqBody path. An unauthenticated attacker can send arbitrarily large request bodies to the public login endpoints, causing the Rancher Manager server process to allocate memory proportional to the supplied body size. With just a few concurrent connections, this can exhaust available memory and terminate the Rancher Manager plane process, making the Rancher API and UI unavailable and interrupting management of all downstream clusters.

Summary
A denial-of-service vulnerability was identified in multiple TLS listeners in Rancher. Both the cattle-cluster-agent component running in downstream clusters and the Rancher server itself use the dynamiclistener library to serve TLS traffic. Without an effective CN filter configured, dynamiclistener automatically appended to each serving certificate any hostname presented via Server Name Indication (SNI) in incoming TLS requests.
An unauthenticated attacker with network access within the affected cluster could send a large number of TLS requests with distinct hostnames, causing the serving certificate to accumulate an unbounded number of Subject Alternative Names (SANs). Eventually, the certificate grows large enough that TLS handshakes fail with an excessive message size error, causing a denial of service on the affected listeners.

CWE
- CWE-522 - Insufficiently Protected Credentials
Summary
A vulnerability has been identified in Fleet's agent-side deployer, which did not filter security-sensitive keys from namespaceLabels in fleet.yaml (or BundleDeployment.spec.options.namespaceLabels) when applying them to the target namespace.
An attacker with git push access to a
Fleet-monitored repository could overwrite Pod Security Standards (PSS)
enforcement labels on a target namespace. This allows the attacker to
weaken admission controls and deploy workloads that PSS policies would
otherwise block.

CWE
- CWE-306 - Missing authentication for critical function
Summary
A Rancher FleetWorkspace admission path allowed side effects to occur in
the Rancher webhook handler for versions 0.7.0 up to 0.7.10, 0.8.0 up to 0.8.7, 0.9.0 up to 0.9.6 and 0.10.0 up to 0.10.7. An unauthenticated attacker with network access to
the in-cluster rancher-webhook service
could submit a crafted admission payload and cause workspace-related
Kubernetes objects to be created with attacker-chosen identity data.
