This is due to the shortcode handler decoding Base64-encoded content and outputting it directly without any sanitization or escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The Base64 encoding allows the payload to bypass WordPress's KSES content filtering at save time, since the encoded string contains no harmful HTML characters."}], "lastModified": "2026-09-21T13:33:33.387", "sourceIdentifier": "security@wordfence.com"}
