CVE-2026-15637Network attack vector

PAM private-key disclosure via unchecked credential identifier

Published Jul 14, 2026 · Updated Jul 14, 2026

Authorization bypass in Devolutions Server 2026.1.22 and earlier and 2026.2.11 and earlier allows remote authenticated users to read private keys. The PAM SSH key and certificate retrieval endpoints accept a direct reference to a credential identifier and return its private key without confirming that the requester is authorized for that credential. Low-privileged access is sufficient, and disclosure is limited to the referenced SSH key or certificate credential.
