If updates are not possible in production environments, we recommend to manually delete it and update as soon as possible.\n\n### Workaround\n\nGiven your context, delete the failing network policy that should be prefixed by `inter-ns-` in the target namespace.","affected":[{"package":{"name":"github.com/ctfer-io/romeo/environment/deploy","ecosystem":"Go","purl":"pkg:golang/github.com/ctfer-io/romeo/environment/deploy"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.2.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/03/GHSA-fgm3-q9r5-43v9/GHSA-fgm3-q9r5-43v9.json"}}],"references":[{"type":"WEB","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":"WEB","url":"https://github.com/ctfer-io/romeo/commit/3bb5e9d9ce1199dfbb90fef8ad79ebdeb0bc5e78"},{"type":"PACKAGE","url":"https://github.com/ctfer-io/romeo"}],"database_specific":{"cwe_ids":["CWE-284"],"github_reviewed":true,"github_reviewed_at":"2026-03-16T20:45:59Z","nvd_published_at":"2026-03-18T23:17:30Z","severity":"HIGH"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H"}]}
