CVE-2026-41063 PUBLISHED

WWBN AVideo is an open source video platform. In versions 29.0 and below, an incomplete XSS fix in AVideo's ParsedownSafeWithLinks class overrides inlineMarkup for raw HTML but does not override inlineLink() or inlineUrlTag(), allowing javascript: URLs in markdown link syntax to bypass sanitization. Commit cae8f0dadbdd962c89b91d0095c76edb8aadcacf contains an updated fix.
