CVE-2025-12640Network attack vector

Author-level media replacement via missing object authorization

Published Jan 8, 2026 · Updated Jan 8, 2026

Missing authorization in Premio Folders 3.1.5 and earlier allows remote authenticated users to replace arbitrary WordPress media files. The handle_folders_file_upload() handler processes a media-replacement request without checking that the caller may modify the targeted attachment. Author-level access is sufficient, and exploitation overwrites an existing Media Library file, changing its content wherever WordPress uses it.
