    Cross-site Scripting (XSS)

    justhtml is an A pure Python HTML5 parser that just works.

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the to_markdown function when serializing attacker-controlled <pre> content. An attacker can execute arbitrary HTML or scripts by crafting input containing backticks and HTML-like text within a sanitized <pre> element, causing the generated Markdown to break out of the intended code block and render raw HTML when processed by Markdown renderers that allow raw HTML.

    How to fix Cross-site Scripting (XSS)?

    Upgrade justhtml to version 1.13.0 or higher.
