CVE-2026-45737
Last modified
CVE-2026-45737 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From 3.2.0 until 3.2.12, 3.3.10, and 3.4.2, Argo CD ServerSideDiff can expose Kubernetes Secret values embedded in the kubectl.kubernetes.io/last-applied-configuration annotation because HideSecretData(target, live, ...) does not fully sanitize ResourceDiff.TargetState and LiveState predicted live Secret objects, allowing sensitive data, stringData, and annotations to appear in UI or CLI diffs. EPSS estimates a 0.28% chance of exploitation in the next 30 days.
