Ultimate YouTube Video & Shorts Player With Vimeo <= 3.3 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Playlist/Video Deletion

The Ultimate YouTube Video & Shorts Player With Vimeo plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the del_ytsingvid() function in all versions up to, and including, 3.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete single playlists.
