Summary

The Cache Purger plugin for WordPress up to version 2.3.20 has an authorization bypass vulnerability that allows authenticated attackers with subscriber-level access or higher to permanently delete the cache-purge audit log (wp-content/purge.log). This is due to insufficient verification of user permissions before performing the action.

Risk Assessment

The organization may lose the entire cache-purge audit history, hindering detection of unauthorized activities and incident analysis. The attack can be executed by any authenticated user, including subscribers, increasing the risk of abuse.

Recommendation

Immediately update the The Cache Purger plugin to the latest available version that fixes this vulnerability. If no update is available, consider temporarily disabling the plugin or restricting access to the admin panel for low-privileged users.

Original NVD description (English source)

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.
