CVE-2026-45738 High · 8.7 CWE-79 Jul 15, 2026

Argo CD: Stored XSS in application link annotations enables developer-to-admin privilege escalation

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Prior to 3.2.12, 3.3.10, and 3.4.2, Argo CD users with application write access can set link.argocd.argoproj.io/* annotations whose pipe-separated values are rendered by ui/src/app/applications/components/application-summary/application-summary.tsx in the Summary tab URLs section as anchor href values without URL validation, allowing javascript: execution in a higher-privileged user's authenticated Argo CD origin session. This issue is fixed in versions 3.2.12, 3.3.10, and 3.4.2.

CVE-2026-45737 Medium · 6.5 CWE-200 Jul 15, 2026

Argo CD: Kubernetes Secret Extraction via ArgoCD ServerSideDiff via sensitive annotations

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. This issue is fixed in versions 3.2.12, 3.3.10, and 3.4.2.

CVE-2026-42880 Critical · 9.6 CWE-200 May 7, 2026

ArgoCD ServerSideDiff is vulnerable to Kubernetes Secret Extraction

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. From versions 3.2.0 to before 3.2.11 and 3.3.0 to before 3.3.9, there is a missing authorization and data-masking gap in Argo CD's ServerSideDiff endpoint that 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. This issue has been patched in versions 3.2.11 and 3.3.9.

CVE-2025-55190 Critical · 9.9 CWE-200 Sep 4, 2025

Argo CD: Project API Token Exposes Repository Credentials

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. In versions 2.13.0 through 2.13.8, 2.14.0 through 2.14.15, 3.0.0 through 3.0.12 and 3.1.0-rc1 through 3.1.1, API tokens with project-level permissions are able to retrieve sensitive repository credentials (usernames, passwords) through the project details API endpoint, even when the token only has standard application management permissions and no explicit access to secrets. This vulnerability does not only affect project-level permissions. Any token with project get permissions is also vulnerable, including global permissions such as: `p, role/user, projects, get, *, allow`. This issue is fixed in versions 2.13.9, 2.14.16, 3.0.14 and 3.1.2.
