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```","published":"2026-03-13T21:27:52.824Z","modified":"2026-10-28T02:30:56.412560518Z","cvss":null,"epss":{"score":0.00262,"percentile":0.17529,"asOf":"2026-08-24"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/ctfer-io/monitoring","fixedVersion":"0.2.1"}],"fix":{"url":"https://github.com/ctfer-io/monitoring/pull/168","label":"ctfer-io/monitoring#168"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32720.json"},{"type":"ADVISORY","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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:56.412560518Z"}}
