AnalysisAIv1 – Jul 15, 2026

Sensitive information disclosure in Devolutions Server 2026.1.x and 2026.2.x lets an authenticated low-privileged user read the private keys of SSH key and certificate PAM credentials belonging to other users. By supplying a credential identifier they should not have access to (an insecure direct object reference), the attacker retrieves secrets the PAM module is supposed to protect. No public exploit identified at time of analysis, and it is not on CISA KEV, but a vendor patch is available. Note: the supplied CVSS vector lists PR:N (unauthenticated) while the description explicitly requires an authenticated low-privileged user — treat this as an authenticated IDOR.

DescriptionCVE.org

Improper authorization in the PAM SSH key and certificate retrieval endpoints in Devolutions Server 2026.2.11, 2026.1.22 allows an authenticated low-privileged user to disclose the private key of an SSH key or certificate PAM credential via a direct object reference to the credential identifier.

Executive ViewAI

Why It Matters

Devolutions Server versions 2026.1.x and 2026.2.x contain a vulnerability allowing any low-privileged user to improperly access SSH private keys and certificate credentials belonging to other users, completely undermining the platform's core credential protection function. This exposure enables lateral movement and privilege escalation through stolen authentication materials that should be inaccessible to unauthorized users. Organizations face immediate risk of credential compromise for any employee with system access at low-privilege levels.

Recommended Action

Within 24 hours, identify all Devolutions Server instances running versions 2026.1.x or 2026.2.x and document which users have low-privilege access to the system. Within 7 days, apply the vendor-released patch to all affected instances and validate successful deployment in a test environment before production rollout. Within 30 days, audit access logs for any unauthorized credential access during the exposure window, rotate all SSH private keys and certificates that may have been accessed by low-privileged users, and verify that the platform's credential isolation controls are functioning as designed.

Business Impact: High
Compensating Controls

Apply vendor patch.
