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
Server-side request forgery (ssrf) in Azure Databricks 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

This is a Server-Side Request Forgery (SSRF) vulnerability in Azure Databricks that allows an unauthorized attacker to elevate privileges over a network. The attacker can potentially make the application perform requests to internal resources, bypassing authentication and authorization controls to escalate privileges.

MitigationApply Azure Databricks security updates when available, implement network segmentation and firewall rules to restrict outbound connections from Databricks resources, and validate that internal service endpoints are not exposed to the Databricks service.

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 your Azure Databricks workspace URL and public accessibility
    In Azure Portal, go to your Databricks resource and note the workspace URL. Check if the workspace is deployed with 'Public IP' enabled or if it has a public endpoint exposed to the internet via Azure networking configuration or Web Application Firewall settings.
    Affected if The Databricks workspace has a public endpoint accessible from the internet without VPN or private link restrictions.
  2. Review outbound network security rules
    Examine Network Security Groups (NSGs) attached to the Databricks VNet, Azure Firewall rules, or any virtual network appliance configurations that govern outbound traffic from the Databricks workspace subnets.
    Affected if Outbound traffic from Databricks is allowed to arbitrary internet addresses or internal cloud metadata endpoints without strict allowlisting.
  3. Verify metadata service endpoint accessibility
    From within a Databricks cluster or notebook, attempt a test connection to the Azure instance metadata service at http://169.254.169.254/ or check NSG rules for any 'allow' rules targeting this IP address.
    Affected if The Databricks compute resources can reach the cloud metadata endpoint at 169.254.169.254, allowing potential retrieval of instance credentials or service principal tokens.
  4. Check if the Databricks workspace requires authentication for API access
    Attempt to send an HTTP request to the Databricks workspace API endpoint (such as /api/2.0/ or /api/2.1/) without providing valid authentication tokens or bearer credentials, observing whether the request is accepted or rejected.
    Affected if The workspace API accepts unauthenticated requests and returns valid responses rather than 401/403 authentication errors.

You are affected if your Azure Databricks workspace is internet-accessible and accepts unauthenticated API requests, especially if outbound network rules permit arbitrary HTTP requests from Databricks resources to internal metadata endpoints.
