CVE-2026-96448 (GCVE-0-2026-96448)

Vulnerability from cvelistv5 – Published: 2026-09-25 07:39 – Updated: 2026-11-06 10:27
VLAI
Title
Keycloak-services: keycloak-services: fgap v2 composite-blind role mapping allows privilege escalation
Summary
A flaw was found in the Fine-Grained Admin Permissions (FGAP v2) feature of Keycloak, an identity and access management solution. The issue occurs when the system checks if a delegated administrator has permission to assign a specific role to a user. Because the check does not look inside composite roles to see what other permissions they contain, an administrator with limited rights can assign a role that secretly includes full administrative control. This allows the attacker to gain complete management access over the entire realm.

Title
node-opcua: Namespace-Level RBAC Fail-Open - Anonymous Write/Call Bypass via Unbound `DefaultRolePermissions
Summary
node-opcua is an OPC UA implementation for TypeScript and Node.js. From 2.42.0 until 2.180.0, namespace-level access control configured through setDefaultRolePermissions is not honored by the runtime enforcement path for nodes without explicit per-node RolePermissions. SessionContext.getApplicableRolePermissions reads a missing or null DefaultRolePermissions metadata value instead of the configured namespace field, and the null result is treated permissively. An anonymous network client can consequently write variables with CurrentWrite access or call bound methods when an operator configured a restrictive namespace default and relied on inheritance. Servers with no declared policy, nodes with explicit per-node permissions, and correctly bound programmatic namespace metadata are outside the authorization-bypass case. This issue is fixed in version 2.180.0.

Title
MISP ACLComponent: Typo in previewEventAttributes ACL key bypasses intended access restriction
Summary
A typo in the MISP ACLComponent access control configuration caused the ACL rule for the previewEventAttributes action to reference the permission string 'theming_enabled*' (with a trailing asterisk) instead of the correct 'theming_enabled'. In the MISP ACL system, the array values define which role or permission grants access to a given controller action. The adjacent entry previewEventObjects correctly uses ['theming_enabled'], confirming the intended restriction. The malformed key 'theming_enabled*' does not match any valid permission identifier, causing the access control check for previewEventAttributes to malfunction. Depending on the ACL evaluation logic, this could result in either unauthorized users gaining access to the previewEventAttributes endpoint (authorization bypass) or legitimate users being denied access (availability impact).  The previewEventAttributes endpoint exposes event attribute data within MISP so an authorization bypass could expose sensitive indicator and attribute data to users who should not have access.

5ac8d1e4dea7 fix: [ACL] typo in previewEventAttributes key c102952ebfab…
Fix summary

The fix corrects the ACL permission key for the previewEventAttributes action from the malformed string 'theming_enabled*' to the correct 'theming_enabled', restoring the intended access control restriction so that only users holding the theming_enabled permission can invoke the endpoint, consistent with the adjacent previewEventObjects entry.

Patch summary

In app/Controller/Component/ACLComponent.php (line 473), the ACL array value for the 'previewEventAttributes' key was changed from ['theming_enabled*'] to ['theming_enabled'], removing the erroneous trailing asterisk that made the permission string non-matching. One line changed, one insertion, one deletion.

CVSS rationale

AV:N: MISP is a network-accessible web application. AC:L: The vulnerability is a static typo in configuration; no race or complex condition is needed. AT:N: No attack target manipulation required. PR:L: The attacker must be an authenticated MISP user to reach the endpoint. UI:N: No victim interaction needed. VC:L: If the ACL bypass is confirmed, an unauthorized user could view event attribute data (limited confidentiality impact). VI:N and VA:N: No integrity or availability impact is evident from the patch. SC/SI/SA:N: No secondary system impact. The overall severity is Low, reflecting a single-endpoint access control misconfiguration with limited data exposure.

Weakness rationale
  • CWE-285 The ACL rule for previewEventAttributes contained a typo ('theming_enabled*') that prevented the authorization check from matching the intended permission, causing the access control mechanism to not enforce the restriction as designed. This is a direct failure of the authorization logic due to a misconfigured rule.
Attack pattern rationale
  • CAPEC-126 The closest plausible attack pattern is Forced Browsing, where an attacker accesses a resource (the previewEventAttributes endpoint) that should be restricted by the ACL. The typo in the ACL key may cause the authorization check to fail to deny access, effectively allowing a user without the theming_enabled permission to reach the endpoint. Uncertainty: the exact ACL evaluation behavior on a non-matching rule (default-deny vs. default-allow) is not visible in the patch, so it is also possible the typo causes a denial rather than a bypass. CAPEC-126 is selected as the best available match for an access-control bypass via misconfiguration.
Assumptions to verify
  • The exact ACL evaluation behavior when a permission string does not match any valid role (default-deny vs. default-allow) is not visible in the patch; the CVSS assumes the more security-relevant interpretation (authorization bypass) but a denial-of-service interpretation is also possible.
  • The affected version range is inferred from the tag boundary v2.5.47 (227 commits after the fix); the exact first affected version is not stated in the patch.
  • The CAPEC-126 mapping is the closest available pattern; the actual attack is a configuration typo rather than an active browsing technique, so the mapping is approximate.
  • The security impact is assumed to be limited to the previewEventAttributes endpoint; no evidence in the patch suggests other endpoints or data stores are affected.
  • The CVSS assumes the endpoint exposes event attribute data viewable by unauthorized users; the actual data sensitivity depends on MISP deployment configuration.

CVE-2026-95754 (GCVE-0-2026-95754)

Title
MISP: Disabled-user check ineffective in pre-authentication TOTP login branch
Summary
In MISP's UsersController login() method, the pre-authentication database query used for the TOTP (two-factor authentication) verification branch did not include the User.disabled column in its SELECT fields list. The query selected only User.password, User.totp, and User.hotp_counter. When the TOTP branch subsequently accessed $unauth_user['User']['disabled'], the key was absent from the result set, producing a PHP 'Undefined array key' warning and causing the expression to evaluate as null (falsy). As a result, the disabled-user guard in the TOTP branch was effectively a no-op: a disabled, TOTP-enrolled user could proceed to the TOTP verification step rather than being rejected at that point.  The commit message explicitly states this was 'harmless in practice' because the subsequent identify() call re-validates the user and would still reject a disabled account.  The practical security impact is therefore minimal, limited to a very small information-disclosure difference in the login response (a TOTP prompt is presented instead of an immediate rejection) and a PHP warning in application logs.

3df982ab192e fix: [login] Fetch User.disabled in the pre-auth TOTP lookup 8ddba4461463…
Fix summary

The fix adds User.disabled to the fields array of the pre-authentication find() query so that the disabled-user check in the TOTP branch reads the actual column value and correctly rejects disabled users before they reach the TOTP verification step, restoring the intended guard behavior.

Patch summary

A single-line change in app/Controller/UsersController.php appends 'User.disabled' to the fields list of the pre-authentication User find() query in the login() method (line 1385), ensuring the disabled flag is present in the result set when the TOTP branch evaluates it.

CVSS rationale

The vulnerability is reachable over the network (AV:N) via the web login endpoint with low complexity (AC:L), no attack target (AT:N), no prior privileges (PR:N), and no user interaction (UI:N). The only potential impact is a very minor confidentiality difference: a disabled, TOTP-enrolled user receives a TOTP prompt instead of an immediate rejection, which could marginally aid account-status enumeration (VC:L). There is no integrity or availability impact (VI:N, VA:N) and no secondary impacts (SC:N, SI:N, SA:N) because the subsequent identify() call still enforces the disabled-user check. The commit message explicitly characterizes the issue as 'harmless in practice.'

Weakness rationale
  • CWE-285 The disabled-user check in the TOTP login branch was ineffective because the required column was not fetched, allowing a disabled user to pass that guard. The subsequent identify() call still enforced the check, limiting the impact. CWE-285 is the narrowest defensible mapping for an authentication-state check that does not function as intended.
Attack pattern rationale
  • CAPEC-1 The closest plausible CAPEC is Brute Force, as the scenario involves an attacker attempting to authenticate using known credentials of a disabled, TOTP-enrolled account. The disabled-user guard that should have blocked the attempt at the TOTP branch was ineffective, allowing the attempt to proceed one step further than intended. This mapping is uncertain because the vulnerability does not enable a full authentication bypass (identify() still rejects the user) and the primary effect is a minor information-disclosure difference in the login response rather than a successful brute-force attack.
Assumptions to verify
  • The commit message states the issue is 'harmless in practice' because identify() re-checks the user; this advisory treats the security impact as minimal (minor information disclosure only).
  • The TOTP feature was introduced in 2023 per the commit message; the exact affected version range is not specified in the patch. The tag boundary v2.5.47 is used as an upper bound for the affected range but is not confirmed as the exact fixed version.
  • CAPEC-1 (Brute Force) is the closest available attack pattern; the actual scenario is a minor authentication-guard bypass rather than a full brute-force attack, so the mapping is approximate.
  • CVSS VC:L is assigned for the marginal information-disclosure difference in the login response; if the CNA determines no meaningful confidentiality impact exists, VC:N would be more appropriate, resulting in a score of 0.0.
  • The PHP version behavior (Warning vs Notice vs Error for undefined array keys) may vary, but in all supported PHP versions the code continues execution with a null value, so the security analysis is unaffected.

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that you perform access control checks related to your business logic. These checks may be different than the access control checks that you apply to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor.

Mitigation MIT-4.4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.

CAPEC-1: Accessing Functionality Not Properly Constrained by ACLs

In applications, particularly web applications, access to functionality is mitigated by an authorization framework. This framework maps Access Control Lists (ACLs) to elements of the application's functionality; particularly URL's for web apps. In the case that the administrator failed to specify an ACL for a particular element, an attacker may be able to access it with impunity. An attacker with the ability to access functionality not properly constrained by ACLs can obtain sensitive information and possibly compromise the entire application. Such an attacker can access resources that must be available only to users at a higher privilege level, can access management sections of the application, or can run queries for data that they otherwise not supposed to.

CAPEC-104: Cross Zone Scripting

An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security.

CAPEC-127: Directory Indexing

An adversary crafts a request to a target that results in the target listing/indexing the content of a directory as output. One common method of triggering directory contents as output is to construct a request containing a path that terminates in a directory name rather than a file name since many applications are configured to provide a list of the directory's contents when such a request is received. An adversary can use this to explore the directory tree on a target as well as learn the names of files. This can often end up revealing test files, backup files, temporary files, hidden files, configuration files, user accounts, script contents, as well as naming conventions, all of which can be used by an attacker to mount additional attacks.

CAPEC-13: Subverting Environment Variable Values

The adversary directly or indirectly modifies environment variables used by or controlling the target software. The adversary's goal is to cause the target software to deviate from its expected operation in a manner that benefits the adversary.

CAPEC-17: Using Malicious Files

An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.

CAPEC-39: Manipulating Opaque Client-based Data Tokens

In circumstances where an application holds important data client-side in tokens (cookies, URLs, data files, and so forth) that data can be manipulated. If client or server-side application components reinterpret that data as authentication tokens or data (such as store item pricing or wallet information) then even opaquely manipulating that data may bear fruit for an Attacker. In this pattern an attacker undermines the assumption that client side tokens have been adequately protected from tampering through use of encryption or obfuscation.

CAPEC-402: Bypassing ATA Password Security

An adversary exploits a weakness in ATA security on a drive to gain access to the information the drive contains without supplying the proper credentials. ATA Security is often employed to protect hard disk information from unauthorized access. The mechanism requires the user to type in a password before the BIOS is allowed access to drive contents. Some implementations of ATA security will accept the ATA command to update the password without the user having authenticated with the BIOS. This occurs because the security mechanism assumes the user has first authenticated via the BIOS prior to sending commands to the drive. Various methods exist for exploiting this flaw, the most common being installing the ATA protected drive into a system lacking ATA security features (a.k.a. hot swapping). Once the drive is installed into the new system the BIOS can be used to reset the drive password.

CAPEC-45: Buffer Overflow via Symbolic Links

This type of attack leverages the use of symbolic links to cause buffer overflows. An adversary can try to create or manipulate a symbolic link file such that its contents result in out of bounds data. When the target software processes the symbolic link file, it could potentially overflow internal buffers with insufficient bounds checking.

CAPEC-5: Blue Boxing

This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.

{'xhtml:b': 'This attack pattern is included in CAPEC for historical purposes.'}

CAPEC-51: Poison Web Service Registry

SOA and Web Services often use a registry to perform look up, get schema information, and metadata about services. A poisoned registry can redirect (think phishing for servers) the service requester to a malicious service provider, provide incorrect information in schema or metadata, and delete information about service provider interfaces.

CAPEC-59: Session Credential Falsification through Prediction

This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

CAPEC-60: Reusing Session IDs (aka Session Replay)

This attack targets the reuse of valid session ID to spoof the target system in order to gain privileges. The attacker tries to reuse a stolen session ID used previously during a transaction to perform spoofing and session hijacking. Another name for this type of attack is Session Replay.

CAPEC-647: Collect Data from Registries

An adversary exploits a weakness in authorization to gather system-specific data and sensitive information within a registry (e.g., Windows Registry, Mac plist). These contain information about the system configuration, software, operating system, and security. The adversary can leverage information gathered in order to carry out further attacks.

CAPEC-668: Key Negotiation of Bluetooth Attack (KNOB)

An adversary can exploit a flaw in Bluetooth key negotiation allowing them to decrypt information sent between two devices communicating via Bluetooth. The adversary uses an Adversary in the Middle setup to modify packets sent between the two devices during the authentication process, specifically the entropy bits. Knowledge of the number of entropy bits will allow the attacker to easily decrypt information passing over the line of communication.

CAPEC-76: Manipulating Web Input to File System Calls

An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

CAPEC-77: Manipulating User-Controlled Variables

This attack targets user controlled variables (DEBUG=1, PHP Globals, and So Forth). An adversary can override variables leveraging user-supplied, untrusted query variables directly used on the application server without any data sanitization. In extreme cases, the adversary can change variables controlling the business logic of the application. For instance, in languages like PHP, a number of poorly set default configurations may allow the user to override variables.

CAPEC-87: Forceful Browsing

An attacker employs forceful browsing (direct URL entry) to access portions of a website that are otherwise unreachable. Usually, a front controller or similar design pattern is employed to protect access to portions of a web application. Forceful browsing enables an attacker to access information, perform privileged operations and otherwise reach sections of the web application that have been improperly protected.
