CVE-2026-41063

Description

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.
