CVE-2026-12123 plugins360 CVE debrief

Who should care

Administrators of WordPress installations with the All-in-One Video Gallery plugin, security teams monitoring for potential internal service exploitation, and developers of dependent plugins or themes.

Technical summary

The All-in-One Video Gallery plugin for WordPress is vulnerable to Server-Side Request Forgery (SSRF) in all versions up to, and including, 4.8.5. The vulnerability is located in the 'vdl' parameter. An authenticated attacker with subscriber-level access or higher can exploit this vulnerability to make web requests to arbitrary locations from the web application. This can be used to query and modify information from internal services. A subscriber-level attacker can plant an internal or loopback URL in the `mp4` post meta of a newly created `aiovg_videos` post via XML-RPC `wp.newPost`, then trigger the unauthenticated `?vdl=<post_id>` endpoint to force the server to fetch that URL and stream the full response body back to the requester.

Defensive priority

Medium priority due to the CVSS score of 6.4 and the potential for internal service exploitation.

Recommended defensive actions

• Update the All-in-One Video Gallery plugin to a version beyond 4.8.5.
• Restrict access to the 'vdl' endpoint to prevent unauthorized requests.
• Monitor server logs for suspicious requests originating from the plugin.
• Implement additional security measures such as web application firewalls to detect and prevent SSRF attacks.
• Regularly review and update the plugin to ensure the latest security patches are applied.
