GNU Mailman before 2.1.35 may allow remote Privilege Escalation.
MEDIUM 4.3EPSS 1.25%
Does this matter?
Lower severity and a low EPSS score (1.25%). Track it; it rarely justifies an emergency change on its own.
Description
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.
