The wpForo Forum plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to and including 3.0.5. This is due to two compounding flaws: the Members::update() method does not validate or restrict the value of file-type custom profile fields, allowing authenticated users to store an arbitrary path instead of a legitimate upload path; and the wpforo_fix_upload_dir() sanitization function in ucf_file_delete() only remaps paths that match the expected pattern, and it is passed directly to the unlink() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). Note: The vulnerability requires a file custom field, which requires the wpForo - User Custom Fields addon plugin.

Arbitrary file deletion in wpForo Forum plugin versions ≤3.0.5 allows authenticated attackers with subscriber-level privileges to delete critical WordPress files including wp-config.php, enabling remote code execution. The vulnerability chains two flaws: unvalidated file paths in custom profile fields and insufficient path sanitization before file deletion. …
