CVE-2025-14435
Mattermost is vulnerable to DoS due to infinite re-renders on API errors
Impact
Mattermost versions 10.11.x <= 10.11.8, 11.1.x <= 11.1.1, 11.0.x <= 11.0.6 fail to prevent infinite re-renders on API errors which allows authenticated users to cause application-level DoS via triggering unbounded component re-render loops.
