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
Authentication bypass by assumed-immutable data in Azure DevOps allows an unauthorized attacker to elevate privileges over a network.

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 · moderate confidence

Authentication bypass vulnerability in Azure DevOps where assumed-immutable data (such as tokens, session identifiers, or static values) can be manipulated to bypass authentication checks, enabling unauthorized attackers to elevate privileges to higher-privileged accounts.

MitigationApply Microsoft security patches for Azure DevOps Server immediately upon release; review and invalidate existing authentication tokens/secrets; enforce multi-factor authentication and principle of least privilege for all user accounts.

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. Confirm Azure DevOps is in use
    Identify whether your environment includes Azure DevOps Services (cloud) or Azure DevOps Server (on-premises). Check for Azure DevOps URLs, installed server components, or integration with Azure DevOps pipelines and repositories.
    Affected if Azure DevOps Services or Azure DevOps Server is deployed in your environment
  2. Review audit logs for authentication anomalies
    Access Azure DevOps audit logs via the Azure DevOps organization settings or via the Analytics service. Look for failed authentication attempts followed by successful ones, or authentication from unexpected IP addresses.
    Affected if Authentication patterns show bypass attempts, privilege escalation, or unauthorized access from unfamiliar sources
  3. Check for unauthorized Personal Access Tokens (PATs)
    In Azure DevOps, go to User Settings > Security > Personal Access Tokens. Review all active PATs for unknown or newly created tokens, especially those with elevated scopes (full access, admin permissions).
    Affected if Unknown PATs exist with broad permissions or PATs were created without user knowledge
  4. Review user account modifications and privilege escalation
    Examine Azure DevOps audit logs for user permission changes, role assignments toGroups like Project Administrators or Collection Administrators, or addition to security groups that were not authorized.
    Affected if User permissions were modified or elevated without proper approval or by unauthorized accounts
  5. Inspect for suspicious service connections or identities
    Check Project Settings > Pipelines > Service Connections and Pipeline Permissions for unfamiliar service principals, service connections with excessive permissions, or newly added identities with write access.
    Affected if Unauthorized service connections exist or unexpected identities have been granted access to pipelines or resources

Your environment is affected if Azure DevOps is deployed and there is any evidence of unauthorized access, privilege escalation, or manipulation of authentication tokens or session data.
