CVE-2026-8407Network attack vector

Authenticated OTP secret disclosure via missing PAM authorization

Published May 12, 2026 · Updated May 12, 2026

Missing authorization in Devolutions Server 2026.1.6.0 through 2026.1.11.0 allows remote authenticated users to obtain OTP secrets. PAM API endpoints return OTP secret keys and recovery codes without enforcing permissions beyond an authenticated account with a PAM license. A PAM-licensed account with no additional permissions is sufficient, and the documented consequence is disclosure of MFA recovery material rather than data modification or service interruption.
