This is due to the use of `strpos()` for substring-based hostname validation instead of strict host comparison in the `ajax_upload_image()` function. This makes it possible for authenticated attackers, with Author-level access and above, to make web requests to arbitrary locations originating from the web application, which can be used to query and modify information from internal services."}], "lastModified": "2026-02-25T14:15:29.980", "sourceIdentifier": "security@wordfence.com"}
