Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Improper authorization in the access request status endpoint in Devolutions Server 2026.2.11, 2026.1.22 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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Improper authorization in the access request status endpoint of Devolutions Server 2026.1.22 and 2026.2.11 allows an authenticated low-privileged user to approve their own pending access request by directly calling the status endpoint, bypassing the mandatory approver review process.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Devolutions Server version
    Access the server administration interface or check the product documentation for the installed version number. This is typically found in the About or System Information section of the management console.
    Affected if The version falls within >= 2026.1.1 and < 2026.1.23.0, or >= 2026.2.4.0 and < 2026.2.12.0
  2. Verify access request module is configured
    Check if the Access Request feature is enabled in Devolutions Server. This feature allows users to request elevated access to resources and requires approver review. Inspect the system configuration or audit logs for any access request-related activity.
    Affected if The access request feature is enabled and in use on the server
  3. Check for low-privileged authenticated users
    Review user accounts and their permission levels in the Devolutions Server user management console. Identify whether there are authenticated users who do not have approver privileges.
    Affected if There are authenticated low-privileged users without approver rights who have access to the access request functionality
  4. Inspect access request audit logs
    Examine the audit or activity logs for access request status changes. Look for any status modifications that were performed directly on the status endpoint rather than through the proper approver workflow.
    Affected if Audit logs show access request status changes performed by non-approver users bypassing the normal approval workflow

The environment is affected if Devolutions Server version is within the vulnerable ranges AND the access request feature is enabled with low-privileged users present who could bypass the approver review process.

Recommended fix High confidence

Upgrade to Devolutions Server 2026.1.23.0 or later for 2026.1.x users; upgrade to 2026.2.12.0 or later for 2026.2.x users

  1. 1. Identify the currently installed Devolutions Server version using the Server Manager or About section
  2. 2. If running 2026.1.x branch (version >= 2026.1.1 and < 2026.1.23.0): Plan upgrade to version 2026.1.23.0 or later
  3. 3. If running 2026.2.x branch (version >= 2026.2.4.0 and < 2026.2.12.0): Plan upgrade to version 2026.2.12.0 or later
  4. 4. Review Devolutions Server release notes for the target version for any prerequisites
  5. 5. Perform a complete backup of the Devolutions Server database before upgrading
  6. 6. Download the installer for the target fixed version from the official Devolutions downloads page
  7. 7. Execute the installer and follow the on-screen upgrade wizard instructions
  8. 8. After upgrade, verify the Server version reflects the fixed release
