Name of the Vulnerable Software and Affected Versions GNU Mailman versions prior to 2.1.36

Description The issue is related to a crafted URL to the "Cgi/options.py" user options page, which can execute arbitrary JavaScript for XSS. This is due to inadequate protection of the web page structure. A remote attacker can exploit this to execute arbitrary JavaScript code.

Recommendations For GNU Mailman versions prior to 2.1.36, update to version 2.1.36 or later to resolve the issue. As a temporary workaround, consider restricting access to the Cgi/options.py page until a patch is available. Avoid using the page for sensitive operations until the issue is resolved.
