CVE-2025-11619Network attack vector

Traffic interception via unvalidated gateway certificate hostname

Published Oct 15, 2025 · Updated Oct 15, 2025

Improper certificate validation in Devolutions Server 2025.3.2 and earlier allows man-in-the-middle attackers to intercept gateway traffic. The gateway TLS validation path accepts certificates whose subject does not match the gateway host name. Exploitation requires control of the server-to-gateway network path; it exposes or alters that traffic, but not sessions traversing the gateway.
