Summary
mailman vulnerabilities
Details

Andre Protas, Richard Cloke, and Andy Nuttall discovered that Mailman did not properly associate cross-site request forgery (CSRF) tokens to specific accounts. A remote attacker could use this to perform a CSRF attack to gain access to another account. (CVE-2021-42097)

Andre Protas, Richard Cloke, and Andy Nuttall discovered that Mailman's cross-site request forgery (CSRF) tokens for the options page are derived from the admin password. A remote attacker could possibly use this to assist in performing a brute force attack against the admin password. (CVE-2021-42096)
