CVE-2022-4270Network attack vector

Permission changes via undisclosed privilege assignment flaw

Published Dec 2, 2022 · Updated Feb 23, 2026

Incorrect privilege assignment in M-Files Web before 22.5.11436.1 allows remote authenticated users to cause unintended permission changes. M-Files has not published the affected request, function, or privilege-assignment operation that mishandles permission data. Reachability requires an already highly privileged account and a separate user action; the disclosed consequence is limited unauthorized data access.
