Summary
Fullchain's Invalid NetworkPolicy enables a malicious actor to pivot into another namespace
Details

Fullchain is an umbrella project for deploying a ready-to-use CTF platform. In versions prior to 0.1.1, due to a mis-written NetworkPolicy, a malicious actor can pivot from a subverted application to any Pod out of the origin namespace. The flawed inter-ns NetworkPolicy breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement. This issue has been fixed in version 0.1.1. To workaround, delete the failing network policy that should be prefixed by inter-ns- in the target namespace.
