CVE-2023-6189Network attack vector

Unauthorized log writes and data exports via API

Published Nov 22, 2023 · Updated Feb 23, 2026

Improper permission handling in M-Files Server before 23.11.13156.0 allows remote authenticated users to run log-write and data-export jobs. Affected M-Files API methods start log-write and data-export jobs for any signed-in user without enforcing the access permissions reserved for authorized accounts. A valid account and network access to the API are required; the reported impact is unauthorized data modification, not disclosure or service interruption.
