Exploitation requires that the attacker's post is governed by a Custom Field Template containing at least one file-type field with the mediaRemove option not enabled, which is the default configuration for file fields."}], "lastModified": "2026-09-22T19:04:55.677", "sourceIdentifier": "security@wordfence.com"}
