{"id":"BIT-kyverno-2026-40868","summary":"kyverno apicall servicecall implicit bearer token injection leaks kyverno serviceaccount token","details":"Kyverno is a policy engine designed for cloud native platform engineering teams. Prior to 1.16.4, kyverno’s apiCall servicecall helper implicitly injects Authorization: Bearer ... using the kyverno controller serviceaccount token when a policy does not explicitly set an Authorization header. Because context.apiCall.service.url is policy-controlled, this can send the kyverno serviceaccount token to an attacker-controlled endpoint (confused deputy). Namespaced policies are blocked from servicecall usage by the namespaced urlPath gate in pkg/engine/apicall/apiCall.go, so this report is scoped to ClusterPolicy and global context usage. This vulnerability is fixed in 1.16.4.","aliases":["CVE-2026-40868","GHSA-q93q-v844-jrqp","GO-2026-5575"],"modified":"2026-09-08T08:47:40.407672968Z","published":"2026-04-23T08:41:53.633Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:kyverno:kyverno:*:*:*:*:*:go:*:*"]},"references":[{"type":"ADVISORY","url":"https://github.com/kyverno/kyverno/security/advisories/GHSA-q93q-v844-jrqp"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40868"}],"affected":[{"package":{"name":"kyverno","ecosystem":"Bitnami","purl":"pkg:bitnami/kyverno"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"1.16.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/kyverno/BIT-kyverno-2026-40868.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"}]}],"schema_version":"1.9.0"}
