Unknown · Gnu Mailman · CVE-2021-42097
**Name of the Vulnerable Software and Affected Versions**
GNU Mailman versions prior to 2.1.35
**Description**
The issue allows remote Privilege Escalation. A `csrf token` value is not specific to a single user account. An attacker can obtain a value within the context of an unprivileged user account, and then use that value in a CSRF attack against an admin, potentially leading to account takeover.
**Recommendations**
For versions prior to 2.1.35, update to version 2.1.35 or later to resolve the issue. As a temporary workaround, consider restricting access to admin accounts or implementing additional CSRF protection measures until a patch is applied.
