CVE-2026-3666

HIGH

wpForo Forum <= 2.4.16 - Authenticated (Subscriber+) Arbitrary File Deletion via Post Body

Title source: cna

Description

The wpForo Forum plugin for WordPress is vulnerable to arbitrary file deletion in all versions up to, and including, 2.4.16. This is due to a missing file name/path validation against path traversal sequences. This makes it possible for authenticated attackers, with subscriber level access and above, to delete arbitrary files on the server by embedding a crafted path traversal string in a forum post body and then deleting the post.
