CVE-2026-15350: CWE-862 Missing Authorization in kevp75 The Cache Purger
The The Cache Purger plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 2.3.20. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to permanently truncate the plugin's cache-purge audit log (wp-content/purge.log), destroying the entire cache-purge audit history. The tcp_log_purge nonce is rendered in the admin bar on frontend pages accessible to all authenticated users including subscribers, meaning any authenticated user possesses the nonce required to trigger the deletion.
AI Analysis
Technical Summary
CVE-2026-15350 is an authorization bypass vulnerability (CWE-862) in The Cache Purger WordPress plugin by kevp75. The plugin does not correctly verify that a user is authorized to perform the cache-purge audit log truncation action. As a result, any authenticated user with subscriber-level privileges or higher can permanently delete the audit log file (wp-content/purge.log). The nonce token (tcp_log_purge) needed to perform this action is accessible to all authenticated users in the admin bar on frontend pages, enabling unauthorized cache-purge audit log deletion. This affects all plugin versions up to and including 2.3.20.
Potential Impact
The vulnerability allows authenticated users with low-level privileges (subscriber or above) to permanently erase the cache-purge audit log, destroying the audit trail of cache purge actions. This impacts the integrity of audit data but does not affect confidentiality or availability of the system. There is no indication of remote code execution or broader system compromise from this vulnerability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated user roles to trusted users only and monitor for suspicious activity related to cache-purge audit log deletion. Avoid granting subscriber-level access to untrusted users. Follow vendor updates for any forthcoming patches or official fixes.
