In version 2.20.2 and earlier, a namespace administrator who can create TriggerAuthentication and ScaledObject resources can set hashiCorpVault.address to a tenant-controlled endpoint and select Kubernetes authentication without an explicit credential. KEDA then uses the operator pod's projected ServiceAccount token and sends it to that endpoint as a Vault login credential. The JWT-shape filter from the prior CVE-2025-68476 remediation accepts the operator token because its subject is a Kubernetes ServiceAccount, so the attacker can obtain the operator's cluster-wide permissions, including broad Secret reads and workload or admission-related operations. This vulnerability is fixed in 2.21.0.","state":0,"publishedAt":"2026-10-14T16:15:15.268+00:00","modifiedAt":"2026-10-20T01:39:03.661+00:00","affected":[{"ecosystem":"Vendor product","name":"keda","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"kedacore\",\n                    \"product\": \"keda\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.21.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://github.com/kedacore/keda/security/advisories/GHSA-637c-6jxx-4rwm","https://github.com/kedacore/keda/commit/1e21cc798dedd079e696cdb45388eddc5e18365d","https://github.com/kedacore/keda/releases/tag/v2.21.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-77524","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-77524","identifiers":["CVE-2026-77524"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
