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":"2026-10-14T17:19:11.147+00:00","modifiedAt":"2026-10-20T02:17:11.973+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","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/commit/1e21cc798dedd079e696cdb45388eddc5e18365d","https://github.com/kedacore/keda/releases/tag/v2.21.0","https://github.com/kedacore/keda/security/advisories/GHSA-637c-6jxx-4rwm"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-77524","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Awaiting Analysis","weaknesses":["CWE-269","CWE-918"],"productCriteria":[],"sourceDates":{"published":"2026-10-14T17:19:11.147","lastModified":"2026-10-20T02:17:11.973"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
