The URL field in a Policy's ServiceCall configuration is not validated, so a user with namespace-level Policy creation permissions can direct Kyverno to make HTTP requests to arbitrary internal resources (e.g., cloud metadata endpoints such as 169.254.169.254 or other tenants' resources). Because Kyverno executes these requests using its cluster-wide high-privilege ServiceAccount (a Confused Deputy problem), the responses—potentially including other tenants' secrets and cloud IAM credentials—are returned in the PolicyReport and can be read by the attacker, breaking multi-tenant isolation.","state":0,"publishedAt":"2026-09-01T12:17:49.407+00:00","modifiedAt":"2026-10-08T16:17:54.93+00:00","affected":[],"metrics":[{"system":"CVSS 4.0 · disclosure@vulncheck.com · Secondary","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:L/SI:L/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X","score":6.9,"severity":"MEDIUM"},{"system":"CVSS 3.1 · disclosure@vulncheck.com · Secondary","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7,"severity":"HIGH"}],"references":["https://github.com/kyverno/kyverno/security/advisories/GHSA-fmqp-4wfc-w3v7","https://www.vulncheck.com/advisories/kyverno-before-1.16.2-ssrf-via-apicall-feature"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-84199","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-918"],"productCriteria":[],"sourceDates":{"published":"2026-09-01T12:17:49.407","lastModified":"2026-10-08T16:17:54.930"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
