CVE-2026-41063: WWBN AVideo has an incomplete fix for CVE-2026-33500: XSS
(updated )
The 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.
