CVE-2026-32737
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.
