    Cross-site Scripting (XSS)

    Affected versions of this package are vulnerable to Cross-site Scripting (XSS) via the clean() function. An attacker can execute arbitrary JavaScript code in the context of the user's browser by submitting crafted HTML containing a formaction attribute with a dangerous URI scheme such as javascript:. This is only exploitable if the application explicitly allows the formaction attribute on submit-capable controls such as <button> or <input> elements.

    How to fix Cross-site Scripting (XSS)?

    There is no fixed version for html5lib.
