What the vulnerability does

01Description

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.

Explanation of Vulnerability in Simple Terms

02Summary

All-in-One Video Gallery versions 4.1.0 through 4.6.4 lack proper authorization checks, allowing authenticated users to modify content they should not have access to. An attacker with a low-privilege account can alter video gallery data without proper permission validation. This affects the integrity of gallery content but does not expose sensitive data or cause service disruption.
