Summary
The All-in-One Video Gallery WordPress plugin before 5.1.0 does not escape a video's stored thumbnail URL in the admin video list, and does not sanitise that value when it is saved outside the plugin's own editor. This is a stored cross-site scripting flaw (CWE-79). A user with as little as the Subscriber role can store script that runs in administrators' browsers. An exploit link is listed in the references.

Description from the CNA
The All-in-One Video Gallery WordPress plugin before 5.1.0 does not escape a video's stored thumbnail URL before outputting it in the admin video list, and does not sanitise that value when it is written outside its own editor, allowing users with a role as low as Subscriber to perform Stored Cross-Site Scripting attacks against administrators.
