Synopsis

The Devolutions Server instance installed on the remote host is affected by multiple vulnerabilities.

Description

The version of Devolutions Server installed on the remote host is prior or equal to 2026.1.22 or 2026.2.0 prior or equal to 2026.2.11. It is, therefore, affected by multiple vulnerabilities, including:

 - Improper authorization in the access request status endpoint allows an authenticated low-privileged user to approve their own pending access request via a direct call to the request status endpoint, bypassing the required approver review. (CVE-2026-15641)

 - Improper authorization in the PAM SSH key and certificate retrieval endpoints 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. (CVE-2026-15637)

 - Insertion of sensitive information into a file in the Recovery Kit response file generation feature allows an attacker with access to the generated response file to obtain the Azure Key Vault client secret in cleartext, even when the option to exclude sensitive data is selected. (CVE-2026-15642)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Devolutions Server version 2026.1.23.0 / 2026.2.12.0 or later.
