Frontend File Manager <= 18.2 - Unauthenticated Post Meta Change

Published Jun 7, 2023 · Updated Apr 8, 2026 · Assigned by Wordfence

Description

The Frontend File Manager plugin for WordPress is vulnerable to Unauthenticated Post Meta Change in versions up to, and including, 18.2. This is due to lacking authentication protections, capability checks, and sanitization, all on the wpfm_file_meta_update AJAX action. This makes it possible for unauthenticated attackers to change the meta data of certain posts and pages.
