CVE-2026-15637: CWE-639 Authorization bypass through User-Controlled key in Devolutions Server
CVE-2026-15637 is an authorization bypass vulnerability in Devolutions Server versions prior to 2026.2.11 and 2026.1.22. It affects the PAM SSH key and certificate retrieval endpoints, allowing an authenticated low-privileged user to access private SSH keys or certificate PAM credentials by manipulating the credential identifier. This improper authorization issue could lead to unauthorized disclosure of sensitive private keys.
AI Analysis
Technical Summary
This vulnerability involves improper authorization (CWE-639) in the PAM SSH key and certificate retrieval endpoints of Devolutions Server. Authenticated users with low privileges can exploit a direct object reference flaw to disclose private keys associated with SSH key or certificate PAM credentials. The issue is present in Devolutions Server versions before 2026.2.11 and 2026.1.22. No CVSS score or vendor remediation information is currently available.
Potential Impact
An authenticated low-privileged user can disclose private SSH keys or certificate PAM credentials, potentially compromising secure access mechanisms that rely on these credentials. This exposure could lead to unauthorized access to systems or data protected by the affected keys.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict access to the PAM SSH key and certificate retrieval endpoints to trusted users only and monitor for suspicious activity related to credential access.
