AI Analysis
Technical Summary
The Broken Link Checker plugin for WordPress suffers from a missing capability check in the ajax_full_status and ajax_dashboard_status functions in all versions up to and including 2.4.4. This CWE-862 (Missing Authorization) vulnerability enables authenticated users with low-level privileges (Subscriber and above) to access plugin status information that should be restricted. The CVSS 3.1 base score is 4.3, reflecting a low complexity attack vector with limited confidentiality impact and no integrity or availability impact. There is no indication of a patch or official vendor advisory at this time.
Potential Impact
An attacker with at least Subscriber-level access can view the plugin's status information without proper authorization. This exposure is limited to information disclosure and does not affect data integrity or availability. The impact is therefore limited to unauthorized read access to plugin status data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict user roles to trusted users only and monitor for suspicious activity involving the Broken Link Checker plugin. Avoid granting Subscriber-level or higher access to untrusted users.
