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
OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.0.4, 1.1.4, and 1.2.0-rc.2, OpenChoreo Workflow Plane templates under samples/getting-started/workflow-templates/ interpolated developer-controlled workflow parameters into shell program text executed through sh -c instead of passing the values through container.env, allowing arbitrary commands to run in workflow pods while affected privileged Podman templates lacked hostUsers: false. This issue is fixed in versions 1.0.4, 1.1.4, and 1.2.0-rc.2.

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 · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-27.

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.

Recommended fix High confidence

Upgrade to 1.0.4, 1.1.4, or 1.2.0-rc.2 depending on your release branch

  1. 1. Identify the current version of OpenChoreo being deployed in your Kubernetes cluster
  2. 2. Determine which release branch you are on (1.0.x, 1.1.x, or 1.2.x)
  3. 3. If on 1.0.x branch, upgrade to version 1.0.4
  4. 4. If on 1.1.x branch, upgrade to version 1.1.4
  5. 5. If on 1.2.x branch, upgrade to version 1.2.0-rc.2
  6. 6. After upgrade, verify workflow templates under samples/getting-started/workflow-templates/ no longer interpolate parameters into shell command text (should use container.env instead)
  7. 7. For Podman templates, confirm hostUsers: false is now set in the template configuration
  8. 8. Test workflow execution to confirm legitimate workflows function correctly after the upgrade

No vendor fix exists The vendor has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
