CVE-2023-0384Network attack vector

Authenticated service interruption via unbounded scheduled-job download

Published Apr 20, 2023 · Updated Feb 23, 2026

Uncontrolled resource consumption in M-Files Server before 23.4.12528.1 allows remote authenticated users to interrupt service. A scheduled job accepts a user-controlled file-download operation without a memory-allocation limit, allowing MFServer to reserve an excessive amount of memory. A valid low-privilege account and network access are required, and no confidentiality or integrity impact is reported.
