CVE-2025-22445Network attack vector

Calls configuration disclosure via misleading settings display

Published Jan 9, 2025 · Updated Jan 9, 2025

Improper exceptional-condition handling in Mattermost 10.0 through 10.2 allows remote authenticated users to misread a Calls security setting. The System Console renders an undefined Calls setting as a definite value instead of accurately representing the missing configuration; Mattermost has not identified the exact setting or rendering path. Low-privileged network access and administrator interaction are required, and the published consequence is limited Calls configuration disclosure.
