{"cve":"CVE-2026-41068","nvd":{"published":"2026-04-24T04:16:19.950","modified":"2026-06-17T10:46:07.213","status":"Analyzed","description":"Kyverno is a policy engine designed for cloud native platform engineering teams. The patch for CVE-2026-22039 fixed cross-namespace privilege escalation in Kyverno's `apiCall` context by validating the `URLPath` field. However, the ConfigMap context loader has the identical vulnerability — the `configMap.namespace` field accepts any namespace with zero validation, allowing a namespace admin to read ConfigMaps from any namespace using Kyverno's privileged service account. This is a complete RBAC bypass in multi-tenant Kubernetes clusters. An updated fix is available in version 1.17.2.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7},"cwes":["CWE-863"],"references":["https://github.com/kyverno/kyverno/commit/bbf3e5c01391d612968440659028ae98e565a777","https://github.com/kyverno/kyverno/security/advisories/GHSA-cvq5-hhx3-f99p","https://github.com/kyverno/kyverno/security/advisories/GHSA-cvq5-hhx3-f99p"],"products":["kyverno:kyverno"],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-41068","score":0.00267,"percentile":0.18841,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cvq5-hhx3-f99p","url":"https://osv.dev/vulnerability/GHSA-cvq5-hhx3-f99p","summary":"Kyverno: Cross-Namespace Read Bypasses RBAC Isolation (CVE-2026-22039 Incomplete Fix)","modified":"2026-09-10T03:51:01.597519877Z","packages":[{"ecosystem":"Go","name":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","ranges":["<=1.17.1"],"fixed":[]}]},{"id":"GO-2026-5337","url":"https://osv.dev/vulnerability/GO-2026-5337","summary":"Kyverno: Cross-Namespace Read Bypasses RBAC Isolation (CVE-2026-22039 Incomplete Fix) in github.com/kyverno/kyverno","modified":"2026-06-26T15:44:22.571743436Z","packages":[{"ecosystem":"Go","name":"github.com/kyverno/kyverno","purl":"pkg:golang/github.com/kyverno/kyverno","ranges":["all versions"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
