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
In Cloud Controller versions prior to 1.46.0, cf-deployment versions prior to 1.3.0, and cf-release versions prior to 283, Cloud Controller accepts refresh tokens for authentication where access tokens are expected. This exposes a vulnerability where a refresh token that would otherwise be insufficient to obtain an access token, either due to lack of client credentials or revocation, would allow authentication.

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

In Cloud Controller versions prior to 1.46.0, cf-deployment prior to 1.3.0, and cf-release prior to 283, the system incorrectly accepts refresh tokens for authentication in places where access tokens are required. This allows authentication using refresh tokens that would otherwise be insufficient to obtain access tokens, either due to missing client credentials or because they have been revoked.

MitigationUpgrade Cloud Controller to version 1.46.0 or later, cf-deployment to 1.3.0 or later, or cf-release to version 283 or later. Additionally, audit for any unauthorized access using refresh tokens during the vulnerable period.

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. Check Cloud Controller API version
    Run `cf curl /v2/info` and look for the 'api_version' field in the response, or query the /v2/capabilities endpoint
    Affected if The version shown is earlier than 1.46.0 (for Capi Release) or the deployment uses Capi Release earlier than 1.46.0
  2. Check cf-deployment version
    Examine the cf-deployment manifest file or run `bosh deployments` to list deployed releases; locate the cf-deployment release and note its version
    Affected if The cf-deployment version is earlier than 1.3.0
  3. Check cf-release version
    Run `bosh releases` or inspect the release manifest to identify the cf-release version number
    Affected if The cf-release version is earlier than 283
  4. Verify Capi Release version directly
    Run `bosh releases | grep -i capi` or check the deployment stemcell manifest for the capi_release version
    Affected if The Capi Release version is earlier than 1.46.0

If any of Cloud Controller (Capi Release), cf-deployment, or cf-release is at a version lower than 1.46.0, 1.3.0, or 283 respectively, the environment is vulnerable to accepting refresh tokens where access tokens are required.
