CVE-2023-0447: Changeset 2844200 for youtube-channel – WordPress Plugin Repository

The My YouTube Channel plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the clear_all_cache function in versions up to, and including, 3.0.12.1. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to clear the plugin’s cache.
