CVE-2025-15516: PLUGINS360 All-In-One Video Gallery

Medium severity, CVSS 4.3. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• PLUGINS360 All-In-One Video Gallery: from 4.1.0, up to and including 4.6.4
