1. Executive Summary

Romeo gives the capability to reach high code coverage of Go ≥1.20 apps by helping to measure code coverage for functional and integration tests within GitHub Actions. Prior to version 0.2.1, due to a mis-written NetworkPolicy, a malicious actor can pivot from the "hardened" namespace to any Pod out of it. This breaks the security-by-default property expected as part of the deployment program, leading to a potential lateral movement. Removing the `inter-ns` NetworkPolicy patches the vulnerability in version 0.2.1. If updates are not possible in production environments, manually delete `inter-ns` and update as soon as possible. Given one's context, delete the failing network policy that should be prefixed by `inter-ns-` in the target namespace.

Compliance & Forensic Hygiene

Beyond immediate remediation, forensic teams must conduct a full sweep of system logs to ensure no persistent backdoors remain within the environment.

Infrastructure & Zero-Trust Risk

The impact of CVE-2026-32737 on enterprise infrastructure cannot be overstated. In the current landscape, we recommend transitioning to a Zero-Trust architecture to prevent lateral movement following an initial breach.
