CVE-2026-67442: CWE-284: Improper Access Control in frangoteam FUXA
FUXA versions prior to 1.3.3 contain an improper access control vulnerability where deleted role identifiers are not fully removed from user role arrays and runtime caches. This can cause users to retain authorization rights that administrators intended to revoke, leading to residual privileges and inconsistent access control states. The issue is fixed in version 1.3.3.
AI Analysis
Technical Summary
The vulnerability in frangoteam's FUXA software affects versions before 1.3.3. When a role is deleted via the DELETE /api/roles endpoint, the role definition is removed from the server-side storage, but the deleted role identifier remains in each user's info.roles array and the runtime usersMap cache. If permission configurations still reference this identifier, affected users may retain authorization rights that should have been revoked. This results in residual privileges, inconsistent access control, and misleading audit logs. The flaw is classified under CWE-284 (Improper Access Control) and CWE-459 (Incomplete Cleanup). The issue is resolved in version 1.3.3.
Potential Impact
Users may retain authorization rights after their roles are deleted, which can lead to residual privileges that administrators intended to remove. This causes inconsistent access control states and may result in inaccurate audit records. The CVSS score is low (2.0) reflecting limited confidentiality impact and requiring high privileges and user interaction for exploitation.
Mitigation Recommendations
Upgrade FUXA to version 1.3.3 or later, where this issue is fixed. There is no indication of alternative mitigations or temporary workarounds. Patch status is not explicitly stated but the fix is included in version 1.3.3.
