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
Authenticated users can upload specifically crafted files to leak server resources. This behavior can potentially be used to run a denial of service attack against Cloud Controller. The Cloud Foundry project recommends upgrading the following releases: * Upgrade capi release version to 1.194.0 or greater * Upgrade cf-deployment version to v44.1.0 or greater. This includes a patched capi release

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

Authenticated Cloud Foundry users can upload specially crafted files that leak server resources, potentially causing denial of service against the Cloud Controller. The vulnerability exists in the capi release component of Cloud Foundry.

MitigationUpgrade capi release to version 1.194.0 or greater, or cf-deployment to v44.1.0 or greater, which includes the patched capi release.

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 capi release version
    Run 'bosh -d deployment-name releases' or check the capi-release deployment version in your BOSH director
    Affected if The installed capi-release version is below 1.194.0 or unknown/undetermined
  2. Check cf-deployment version
    Run 'cf deployment' or inspect your cf-deployment manifest for the release version
    Affected if Using cf-deployment version below v44.1.0
  3. Confirm Cloud Controller component presence
    Verify that the capi-release is deployed by checking 'bosh -d cf deployments' or 'cf api' endpoint responds
    Affected if Cloud Foundry capi-release is present in the environment
  4. Identify authenticated user access
    Review Cloud Foundry user accounts and their permissions via 'cf users' or UAA console
    Affected if Any authenticated users exist in the Cloud Foundry environment
  5. Monitor file upload resource consumption
    Check Cloud Controller logs (cc.log) for unusual patterns: high CPU/memory from file staging endpoints, excessive temporary file creation in /tmp or /var/vcap/data
    Affected if Unexplained resource exhaustion tied to package upload or droplet staging operations

If your deployed capi-release version is below 1.194.0 (or cf-deployment below v44.1.0) and authenticated users can upload application packages, the environment is likely affected by this resource leak vulnerability.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade capi release to version 1.194.0 or greater, or cf-deployment to v44.1.0 or greater, which includes the patched capi release.

Recommended fix High confidence

capi release >= 1.194.0 or cf-deployment >= v44.1.0

  1. Identify the current version of capi release and/or cf-deployment in your Cloud Foundry deployment
  2. To patch the vulnerability, either: Upgrade capi release to version 1.194.0 or greater
  3. Alternatively: Upgrade cf-deployment to version v44.1.0 or greater (which includes the patched capi release)
  4. After upgrading, verify the Cloud Controller components are running correctly
  5. Monitor system resources to confirm the resource consumption vulnerability is mitigated
