CVE-2025-2091Network attack vector

Victim redirection via crafted PDF URL

Published Jun 16, 2025 · Updated Feb 23, 2026

Open redirection in M-Files Mobile before 25.6.0 allows remote authenticated users to send victims to untrusted URLs via crafted PDFs. M-Files has not disclosed which PDF field or mobile-client handler accepts the untrusted URL or how validation fails. The attacker must be able to add content to a vault, and a victim must interact with the PDF; the bounded consequence is a request to an attacker-chosen URL.
