Vulnerability from github – Published: 2026-01-16 12:30 – Updated: 2026-01-21 16:19

Summary

Mattermost is vulnerable to DoS due to infinite re-renders on API errors

Details

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.

Severity ?

6.8 (Medium)
