CVE-2026-52466: n/a
Open Library Foundation VuFind v11.0.3 and v4.1 is vulnerable to toInorrect Access Control. The application fails to stop processing an incoming request in VuFind\Controller\AbstractBase::validateAccessPermission after it has found that controller level access permissions do not allow access to the requested function. The requester receives a response indicating that access was denied, but the actual function is executed regardless of that.
AI Analysis
Technical Summary
VuFind versions 11.0.3 and 4.1 contain an access control flaw in the AbstractBase controller's validateAccessPermission method. When access permissions deny a request, the application fails to halt further processing, allowing the protected function to execute despite the denial response. This results in unauthorized execution of functions that should be blocked by access controls.
Potential Impact
An attacker or unauthorized user can trigger functions that should be restricted, potentially leading to unauthorized actions or data exposure. The system misleadingly indicates access denial while still performing the requested operation, undermining the intended security controls.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to vulnerable versions and monitor for unusual activity related to unauthorized function execution.
