DescriptionNVD

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All Argo CD versions starting with 2.3.0-rc1 and prior to 2.3.17, 2.4.23 2.5.11, and 2.6.2 are vulnerable to an improper authorization bug which allows users who have the ability to update at least one cluster secret to update any cluster secret. The attacker could use this access to escalate privileges (potentially controlling Kubernetes resources) or to break Argo CD functionality (by preventing connections to external clusters). A patch for this vulnerability has been released in Argo CD versions 2.6.2, 2.5.11, 2.4.23, and 2.3.17. Two workarounds are available. Either modify the RBAC configuration to completely revoke all clusters, update access, or use the destinations and clusterResourceWhitelist fields to apply similar restrictions as the namespaces and clusterResources fields.

AnalysisAI

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Rated high severity (CVSS 8.5), this vulnerability is remotely exploitable. This Incorrect Authorization vulnerability could allow attackers to bypass authorization checks to access restricted resources.
