CVE-2026-32768: Chall-Manager's invalid NetworkPolicy enables a malicious actor to pivot into another namespace
(updated )
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.
