This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes such as 'color', 'podcast_id', and 'podcast_slug'. These attributes are directly concatenated into inline JavaScript within single-quoted string arguments without any escaping or sanitization, allowing an attacker to break out of the JavaScript string context. 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": "2026-03-23T14:32:02.800", "sourceIdentifier": "security@wordfence.com"}
