CVE-2026-32737

Romeo's invalid NetworkPolicy enables a malicious actor to pivot into another namespace

Published Mar 18, 2026 CVSS 4.0 · 7.9 High EPSS < 1% KEV · Not listed
Description
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.
