What is CVE-2026-120408?

The All-in-One Video Gallery plugin for WordPress before version 5.1.0 fails to properly escape video thumbnail URLs when displaying them in the admin video list. Additionally, the plugin does not sanitize these URLs when written outside its editor, empowering users with minimal permissions, such as Subscribers, to conduct Stored Cross-Site Scripting attacks targeting administrators. This vulnerability can enable the execution of malicious scripts, compromising the integrity and security of the WordPress installation.

Affected Version(s)

All-in-One Video Gallery 0 < 5.1.0
