The Meow Gallery plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.5.4 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 author-level access and above, to enumerate and read metadata — including post ID, title, date, author, and status — of all private and draft posts on the site, including those authored by other users.
