This makes it possible for authenticated attackers, with Editor-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The attacker can upload a benign image file, then use the `update_media_metadata` endpoint to rename it to a PHP file, creating an executable PHP file in the uploads directory."}], "lastModified": "2026-01-29T16:31:35.700", "sourceIdentifier": "security@wordfence.com"}
