Summary
Chall-Manager's invalid NetworkPolicy enables a malicious actor to pivot into another namespace
Workaround
Given your context, delete the failing network policy that should be prefixed by inter-ns- in the target namespace.
You can use the following to delete all matching network policy. If unsure of the outcome, please do it manually.
for ns in $(kubectl get ns -o jsonpath='{.items[*].metadata.name}' | tr ' ' '\n' | grep '^cm-target-'); do
kubectl -n "$ns" get networkpolicy -o name \
| grep '^networkpolicy.networking.k8s.io/inter-ns-' \
| xargs -r kubectl -n "$ns" delete
done
Impact
Due to a mis-written NetworkPolicy, a malicious actor can pivot from an instance to any Pod out of the origin namespace.
This breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement.
In the specific case of sdk/kubernetes.Kompose it does not isolate the instances.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Removing the inter-ns NetworkPolicy patches the vulnerability. If updates are not possible in production environments, we recommend to manually delete it and update as soon as possible.
Frequently Asked Questions
- What is CVE-2026-32768? CVE-2026-32768 is a high-severity security vulnerability in github.com/ctfer-io/chall-manager/deploy (go), affecting versions < 0.6.5. It is fixed in 0.6.5.
- Which packages are affected by CVE-2026-32768?
github.com/ctfer-io/chall-manager/deploy(go) (versions < 0.6.5)github.com/ctfer-io/chall-manager/sdk(go) (versions < 0.6.5)
- Is there a fix for CVE-2026-32768? Yes. CVE-2026-32768 is fixed in 0.6.5. Upgrade to this version or later.
- Is CVE-2026-32768 exploitable, and should I be worried? Whether CVE-2026-32768 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-32768 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
