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
Snyk has identified a remote code execution (RCE) vulnerability in all versions of Code Agent. The vulnerability enables an attacker to execute arbitrary code within the Code Agent container. Exploiting this vulnerability would require an attacker to have network access to the Code Agent within the deployment environment. External exploitation of this vulnerability is unlikely and depends on both misconfigurations of the cluster and/or chaining with another vulnerability. However, internal exploitation (with a cluster misconfiguration) could still be possible.

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

Remote code execution vulnerability in Snyk Code Agent allowing arbitrary code execution within the container. Exploitation requires network access to the Code Agent component within the deployment environment. External exploitation is unlikely without cluster misconfigurations or chaining with other vulnerabilities.

MitigationImplement network segmentation and restrict network access to Code Agent through Kubernetes network policies; monitor for available vendor patches and update Code Agent when fixes become available.

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 Snyk Code Agent deployment
    List all containers/pods in the cluster and search for those with 'snyk' or 'code-agent' in the name or image path. Run: kubectl get pods --all-namespaces -o jsonpath='{range .items[*]}{.metadata.name}{.spec.containers[*].image}{"\n"}{end}' | grep -i snyk
    Affected if Snyk Code Agent container or pod is found running in the environment
  2. Determine Code Agent version
    Check the image version tag of the identified Code Agent container. Run: kubectl get pods -n <namespace> -o jsonpath='{.spec.containers[*].image}' for pods containing snyk code-agent
    Affected if The installed version matches or precedes the patched version (compare your version to vendor release notes for the fix)
  3. Verify network exposure of Code Agent
    Inspect Kubernetes network policies or service configurations to determine if Code Agent pods are accessible beyond their intended namespace. Check service type and ingress rules: kubectl get svc -A | grep -i code-agent and kubectl get networkpolicies -A
    Affected if Code Agent has a ClusterIP/LoadBalancer/NodePort service or no network policy restricting access, making it reachable from other pods or external networks
  4. Check for cluster-wide RBAC permissions
    Review RBAC roles that grant broad access to the namespace where Code Agent runs: kubectl get rolebindings,clusterrolebindings -A -o jsonpath='{range .items[?(@.subjects[?(@.kind=="ServiceAccount")])]}{.metadata.name}{.subjects[?(@.kind=="ServiceAccount")]}{"\n"}{end}'
    Affected if Service accounts in other namespaces or cluster-wide have permissions that could be chained to reach Code Agent

Environment is affected if Snyk Code Agent is deployed with a version prior to the vendor patch AND the Code Agent component is network-accessible from untrusted contexts beyond its immediate deployment scope.
