NVD Description

Note: Versions mentioned in the description apply only to the upstream mailman:2.1/mailman package and not the mailman:2.1/mailman package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

GNU Mailman before 2.1.35 may allow remote Privilege Escalation. A certain csrf_token value is derived from the admin password, and may be useful in conducting a brute-force attack against that password.
