CVE-2023-40025

In Argo CD versions 3.2.0 to 3.2.10 and 3.3.0 to 3.3.8, there is a missing authorization and data-masking gap in the ServerSideDiff endpoint. This allows an attacker with read-only access to extract plaintext Kubernetes Secret data from etcd via the Kubernetes API server's Server-Side Apply dry-run mechanism.

A vulnerability in Argo CD allows users with application write access to set link.argocd.argoproj.io/* annotations whose pipe-separated values are rendered as anchor href values in the Summary tab URLs section without URL validation, enabling JavaScript execution in a higher-privileged user's authenticated session. The issue is fixed in versions 3.2.12, 3.3.10, and 3.4.2.

Argo CD ServerSideDiff in versions 3.2.0 through 3.2.12, 3.3.10, and 3.4.2 fails to properly sanitize Kubernetes Secret data, potentially exposing sensitive values including those in the kubectl.kubernetes.io/last-applied-configuration annotation. This allows sensitive data to appear in the UI or CLI diffs.

A flaw was identified in Argo CD, the GitOps engine used by Red Hat OpenShift GitOps, that could allow an unauthenticated attacker with network access to the Argo CD repo-server to achieve remote code execution. Under certain conditions, the attacker may then manipulate cached data to deploy malicious Kubernetes resources to managed clusters, potentially resulting in complete cluster compromise.

A vulnerability in Argo CD versions 3.2.0 through 3.2.10 and 3.3.0 through 3.3.8 allows reading cleartext Kubernetes Secret data via the ServerSideDiff feature.

An access control issue in Argo CD v2.4.12 and below allows unauthenticated attackers to enumerate existing applications. The problem stems from missing proper access controls.
