CVE-2022-31105: Argo CD's certificate verification is skipped for connections to OIDC providers

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with version 0.4.0 and prior to 2.2.11, 2.3.6, and 2.4.5 is vulnerable to an improper certificate validation bug which could cause Argo CD to trust a malicious (or otherwise untrustworthy) OpenID Connect (OIDC) provider. A patch for this vulnerability has been released in Argo CD versions 2.4.5, 2.3.6, and 2.2.11. There are no complete workarounds, but a partial workaround is available. Those who use an external OIDC provider (not the bundled Dex instance), can mitigate the issue by setting the `oidc.config.rootCA` field in the `argocd-cm` ConfigMap. This mitigation only forces certificate validation when the API server handles login flows. It does not force certificate verification when verifying tokens on API calls.

Security readout for executives and security teams

Plain-English summary

Argo CD could fail to verify TLS certificates when talking to an external OIDC identity provider. In affected versions, a malicious or untrusted provider could be trusted during authentication-related flows, putting Kubernetes delivery control at risk.

Executive priority

Prioritize remediation where Argo CD controls production Kubernetes delivery and uses external OIDC. The issue can undermine trust in authentication infrastructure, but the available source bundle does not prove active exploitation.

Technical view

CVE-2022-31105 is improper certificate validation in Argo CD OIDC provider connections. Affected ranges are >=0.4.0 <2.2.11, >=2.3.0 <2.3.6, and >=2.4.0 <2.4.5. Fixed releases are 2.2.11, 2.3.6, and 2.4.5. CWEs include CWE-295 and CWE-599.

Likely exposure

Highest exposure is Argo CD deployments using an external OIDC provider rather than only the bundled Dex instance. The source bundle does not identify affected managed services or downstream distributions.

Exploitation context

The CVSS score is 8.3 with network attack vector, high complexity, no privileges required, user interaction required, changed scope, and high impact. The bundle does not show CISA KEV listing or cited evidence of active exploitation.

Researcher notes

Focus validation on certificate verification behavior in OIDC paths and whether the deployment uses external OIDC. The named workaround only affects API-server login flows and does not force certificate verification for token validation on API calls.

Mitigation direction

  • Upgrade Argo CD to 2.2.11, 2.3.6, 2.4.5, or a later fixed release.
  • For external OIDC, set oidc.config.rootCA in argocd-cm as a partial temporary mitigation.
  • Do not treat rootCA as complete; token verification on API calls remains unaffected.
  • Review the Argo CD advisory and release notes before applying production changes.

Validation and detection

  • Inventory Argo CD versions and flag affected 0.4.0, 2.2.x, 2.3.x, and 2.4.x deployments.
  • Review argocd-cm for external OIDC configuration and oidc.config.rootCA presence.
  • Confirm deployed images are 2.2.11, 2.3.6, 2.4.5, or later fixed releases.
  • Check authentication logs for unusual identity-provider or certificate-related events.
