The Frontend File Manager Plugin WordPress plugin through 23.6 does not sanitise nor escape a filename submitted to the frontend file-rename endpoint before storing it as post meta and rendering it back on the admin File Manager listing, leading to a Stored Cross-Site Scripting vulnerability exploitable by users with Subscriber-level access and above against an administrator viewing the file management interface.
