CVE-2025-6741Network attack vector

Authenticated entry theft via attachment authorization bypass

Published Jul 22, 2025 · Updated Nov 25, 2025

Improper access control in Devolutions Server through 2025.1.11 and 2025.2.2 through 2025.2.4 allows remote authenticated users to steal entries. The secure-message attachment feature fails to enforce entry-level authorization before returning an attached entry outside the requester's permitted set. A valid account and a crafted attachment request are required; the documented consequence is disclosure of stored entries, not modification or service interruption.
