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 monitoring namespace.\nYou can use the following to delete all matching network policy. If unsure of the outcome, please do it manually.\n\n```bash\nfor ns in $(kubectl get ns -o jsonpath='{.items[*].metadata.name}' | tr ' ' '\\n' | grep '^monitoring-'); do\n  kubectl -n \"$ns\" get networkpolicy -o name \\\n  | grep '^networkpolicy.networking.k8s.io/inter-ns-' \\\n  | xargs -r kubectl -n \"$ns\" delete\ndone\n```","affected":[{"package":{"name":"github.com/ctfer-io/monitoring","ecosystem":"Go","purl":"pkg:golang/github.com/ctfer-io/monitoring"},"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-7x23-j8gv-v54x/GHSA-7x23-j8gv-v54x.json"}}],"references":[{"type":"WEB","url":"https://github.com/ctfer-io/monitoring/security/advisories/GHSA-7x23-j8gv-v54x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32720"},{"type":"WEB","url":"https://github.com/ctfer-io/monitoring/pull/168"},{"type":"WEB","url":"https://github.com/ctfer-io/monitoring/commit/5404a11863b32b14ee5c62d1215352ab519d4edb"},{"type":"PACKAGE","url":"https://github.com/ctfer-io/monitoring"},{"type":"WEB","url":"https://github.com/ctfer-io/monitoring/releases/tag/v0.2.1"}],"database_specific":{"cwe_ids":["CWE-284"],"github_reviewed":true,"github_reviewed_at":"2026-03-13T20:58:28Z","nvd_published_at":"2026-03-16T14:19:43Z","severity":"HIGH"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:N/SC:H/SI:H/SA:H"}]}
