Summary
Improper certificate validation on LDAPS connections to Active Directory in Devolutions Server 2026.2.16 and earlier allows a network-positioned attacker to intercept privileged directory service credentials via a spoofed domain controller certificate. The vulnerability enables a man-in-the-middle attack.
Risk Assessment
A network attacker can impersonate a domain controller and intercept high-privilege credentials, potentially leading to full compromise of Active Directory and the entire infrastructure. The consequences can be critical for the organization's security.
Recommendation
Update Devolutions Server to a version later than 2026.2.16 if available. Until patched, consider disabling LDAPS or implementing additional certificate verification mechanisms.

- CVE-2026-119636High
A vulnerability in Devolutions Server (versions 2025.3.2.0 through 2026.2.22.0) causes improper release of expired privileged access checkouts in the PAM scheduled check-in task. An authenticated user with checkout rights on a PAM account can retain access to that account on the target system after the checkout expires if a backlog of 21 or more newer active checkouts prevents the expired checkout from being checked in and its password from being rotated.
