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."

En las versiones 29.0 e inferiores, una corrección XSS incompleta en la clase “ParsedownSafeWithLinks” de AVideo anula “inlineMarkup” para HTML sin procesar, pero no anula “inlineLink()” ni “inlineUrlTag()”, lo que permite que las URL “javascript_disabled: ” en la sintaxis de enlaces de markdown eludan la sanitización. El commit cae8f0dadbdd962c89b91d0095c76edb8aadcacf contiene una corrección actualizada."
