CVE-2025-0635Network attack vector

Unauthenticated service slowdown via excessive input processing

Published Jan 23, 2025 · Updated Feb 23, 2026

Resource exhaustion in M-Files Server before 25.1.14445.5 allows remote attackers to slow server processing via crafted input values. M-Files states that certain input values require excessive processing time, but it does not identify the affected parser, endpoint, or input field. No authentication is required; the resulting service interrupt degrades processing speed without preventing the system from operating fully.
