CVE-2026-75823: CWE-269 Improper Privilege Management in User Frontend
The User Frontend WordPress plugin before 4.3.12 does not prevent tampering with the role assigned by its registration form, allowing unauthenticated users to register with a higher privileged role, such as Editor. This affects installations running a PHP build where the sodium extension is unavailable, and where a registration page has been configured. The administrator role cannot be obtained this way.
AI Analysis
Technical Summary
CVE-2026-75823 is an improper privilege management vulnerability (CWE-269) in the User Frontend WordPress plugin versions >=3.5.29 and <4.3.12. The plugin fails to prevent tampering with the user role assigned during registration, allowing unauthenticated users to register with higher privileges like Editor. This flaw is conditional on the PHP sodium extension being unavailable and the presence of a configured registration page. The vulnerability does not allow escalation to the administrator role.
Potential Impact
Unauthenticated users can register accounts with elevated privileges such as Editor, potentially allowing them to perform actions reserved for higher-privileged users. However, the administrator role is not accessible via this vulnerability, limiting the scope of privilege escalation.
Mitigation Recommendations
No official patch or remediation details are provided in the input data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, administrators should consider disabling registration pages or ensuring the PHP sodium extension is enabled to mitigate this issue.
