WWBN AVideo has incomplete fix for CVE-2026-33500 (XSS)
MEDIUM 5.9EPSS 0.3%
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.
