Calum Hutton and the Mailman team discovered a cross site scripting and information leak vulnerability in the user options page. A remote attacker could use a crafted URL to steal cookie information or to fish for whether a user is subscribed to a list with a private roster. For the oldstable distribution (jessie), this problem has been fixed in version 2.1.18-2+deb8u2. For the stable distribution (stretch), this problem has been fixed in version 2.1.23-1+deb9u2. We recommend that you upgrade your mailman packages. For the detailed security status of mailman please refer to its security tracker page at: https://security-tracker.debian.org/tracker/mailman
