CVE-2022-1332Network attack vector

Restricted-admin disclosure via missing permission checks

Published Apr 13, 2022 · Updated Dec 6, 2024

Improper privilege management in affected Mattermost releases allows remote authenticated users to read server logs and configuration. The affected API fails to enforce restricted custom-admin permissions before returning server logs and config.json contents. Mattermost has not identified the endpoint or published the faulty authorization logic; exploitation requires an authenticated member assigned a restricted custom administrator role.
