{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/83980?format=json","vulnerability_id":"VCID-fhxw-xm4n-byfk","summary":"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":[{"alias":"CVE-2026-40868"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://github.com/kyverno/kyverno/security/advisories/GHSA-q93q-v844-jrqp","reference_id":"GHSA-q93q-v844-jrqp","reference_type":"","scores":[{"value":"8.1","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N"},{"value":"Track*","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:T/P:M/B:A/M:M/D:R/2026-04-22T13:34:55Z/"}],"url":"https://github.com/kyverno/kyverno/security/advisories/GHSA-q93q-v844-jrqp"}],"weaknesses":[{"cwe_id":922,"name":"Insecure Storage of Sensitive Information","description":"The product stores sensitive information without properly limiting read or write access by unauthorized actors."}],"exploits":[],"severity_range_score":"8.1 - 8.1","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-fhxw-xm4n-byfk"}
