CVE-2026-0932Network attack vector

Unauthenticated blind SSRF via legacy co-authoring connections

Published Apr 1, 2026 · Updated Apr 1, 2026

Blind SSRF in M-Files Server before 26.3.15818.5 allows remote attackers to make the server send HTTP GET requests to arbitrary URLs. Legacy connection methods in the document co-authoring feature accept an attacker-controlled URL and issue a server-side GET request without restricting its destination. No authentication or user interaction is required; successful abuse reveals the server IP address and moderately degrades server performance, while the request carries no other sensitive data.
