All-in-One Video Gallery 4.1.0 - 4.6.4 - Missing Authorization to Authenticated (Subscriber+) Limited User Meta Update

The All-in-One Video Gallery plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ajax_callback_store_user_meta() function in versions 4.1.0 to 4.6.4. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary string-based user meta keys for their own account.
