{"id":"CVE-2026-32737","aliases":["GHSA-fgm3-q9r5-43v9","GO-2026-4714"],"url":"https://o3.security/vulnerability/CVE-2026-32737","summary":"Romeo's invalid NetworkPolicy enables a malicious actor to pivot into another namespace","details":"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.","published":"2026-03-18T22:23:09.952Z","modified":"2026-08-07T11:50:52.820863118Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/ctfer-io/romeo/environment/deploy","fixedVersion":"0.2.1"}],"fix":{"url":"https://github.com/ctfer-io/romeo/commit/3bb5e9d9ce1199dfbb90fef8ad79ebdeb0bc5e78","label":"ctfer-io/romeo@3bb5e9d"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32737.json"},{"type":"ADVISORY","url":"https://github.com/ctfer-io/romeo/security/advisories/GHSA-fgm3-q9r5-43v9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32737"},{"type":"FIX","url":"https://github.com/ctfer-io/romeo/commit/3bb5e9d9ce1199dfbb90fef8ad79ebdeb0bc5e78"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:50:52.820863118Z"}}
