CVE-2025-11176Network attack vector

Authenticated cross-author image manipulation via unchecked post key

Published Oct 15, 2025 · Updated Oct 15, 2025

Authorization bypass in Quick Featured Images 13.7.2 and earlier allows remote authenticated users to alter other authors' featured images. The qfi_set_thumbnail and qfi_delete_thumbnail AJAX handlers accept a user-controlled post key and set or remove its thumbnail without validating that the requester may modify that post. Author-level access is sufficient; the bounded consequence is unauthorized modification or removal of featured images on posts owned by other users.
