A Cross-Site Request Forgery (CSRF) attack can be performed in mailman due to a CSRF token bypass. CSRF tokens are not checked against the right user and a token created by one user can be used by another one to perform a request, effectively bypassing the protection provided by CSRF tokens. A remote attacker with an account on the mailman system can use this flaw to perform a CSRF attack and perform operations on behalf of the victim user.
Mitigation
Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
