This is due to the use of regex-based HTML processing (`preg_replace`) that does not properly handle HTML attribute boundaries when replacing `src` attributes, allowing crafted content inside a `class` attribute value to be promoted to real DOM attributes after processing. 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."}], "lastModified": "2026-06-17T10:30:44.847", "sourceIdentifier": "security@wordfence.com"}
