What is CVE-2025-3230?

Mattermost suffers from a vulnerability where personal access tokens are not invalidated when a user is deactivated. This flaw allows users who have been deactivated to still access the system seamlessly by exploiting previously issued tokens. Attackers could potentially use this to retain unauthorized access, posing a serious risk to the integrity of system security. It is recommended that users and administrators ensure proper token management and updates to mitigate this issue.
