Read the original description
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.
