CVE-2022-4858

Token disclosure via configuration-dependent sensitive logging

Published Dec 30, 2022 · Updated Feb 23, 2026

Sensitive-data logging in M-Files Server before 22.10.11846.0 allows local users to obtain sensitive tokens from stored logs. Under specific configurations, the server writes sensitive tokens to log files that are expected not to contain them; M-Files has not identified the responsible component or setting. Access to the server or other log storage is required, and a role able to read those files can recover tokens without altering data or interrupting service.
