CVE-2026-22727
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 · uneditedUnprotected internal endpoints in Cloud Foundry Capi Release 1.226.0 and below, and CF Deployment v54.9.0 and below on all platforms allows any user who has bypassed the firewall to potentially replace droplets and therefore applications allowing them to access secure application information.
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 confidenceCloud Foundry Capi Release 1.226.0 and below, and CF Deployment v54.9.0 and below contain unprotected internal API endpoints. When an attacker bypasses firewall controls, they can access these internal endpoints to replace application droplets (the staged application binaries) and obtain sensitive application information stored within the Cloud Foundry platform.

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 checksWork through these to decide whether this CVE applies to you.
-
Check Capi Release versionRun 'cf curl /v2/info' or consult the Cloud Foundry deployment manifest to identify the Capi Release version currently deployedAffected if The installed Capi Release version is 1.226.0 or lower
-
Check CF Deployment versionConsult the CF Deployment manifest file or run 'bosh deployments' to identify the CF Deployment version currently deployedAffected if The installed CF Deployment version is v54.9.0 or lower
-
Verify network segmentation for internal APIsReview firewall rules, security groups, and network policies to determine whether internal Cloud Foundry API endpoints (such as those on the CC-Bridge or Capi components) are exposed to untrusted networksAffected if Internal API endpoints are accessible from networks outside the trusted internal network segment
-
Test internal endpoint accessibilityAttempt to access internal Capi endpoints from an untrusted network segment using curl or similar tool to the internal API URLs (e.g., internal CC APIs) without authenticationAffected if Internal endpoints respond without requiring authentication or network-level access controls
You are affected if your Capi Release is 1.226.0 or below OR your CF Deployment is v54.9.0 or below AND your network segmentation allows unauthorized access to internal API endpoints.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to Capi Release 1.227.0 or higher and CF Deployment v55.0.0 or higher. Additionally, enforce proper network segmentation and firewall rules to prevent unauthorized access to internal endpoints.
Capi Release > 1.226.0, CF Deployment > v54.9.0
- Upgrade Cloud Foundry Capi Release to a version above 1.226.0
- Upgrade Cloud Foundry CF Deployment to a version above v54.9.0
- After upgrading, verify that internal endpoints now require appropriate authentication
- Confirm that droplet replacement operations require proper authentication credentials
