When a shoutbox form submission fails the nonce check (or `shouttext` is empty, or the user is unable to save), the raw POST value is echoed back into a `<textarea>` element using `printf('%s', ...)` with no HTML escaping. This makes it possible for unauthenticated attackers to execute arbitrary web scripts in the browser of an authenticated victim (Subscriber-level or higher) who is tricked into submitting a crafted POST request to a page that contains the Shoutbox widget."}], "lastModified": "2026-08-12T21:00:37.147", "sourceIdentifier": "security@wordfence.com"}
