Esta página presenta datos de fuentes públicas de vulnerabilidades. Consulta el aviso original antes de actualizar.
Versions of `showdown` prior to 1.9.1 are vulnerable to [Reverse Tabnabbing](https://www.owasp.org/index.php/Reverse_Tabnabbing). The package uses `target='_blank'` in anchor tags, allowing attackers to access `window.opener` for the original page when opening links. This is commonly used for phishing attacks. ## Recommendation Upgrade to version 1.9.1 or later.
