CVE-2022-31034: Insecure entropy in argo-cd

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of Argo CD starting with v0.11.0 are vulnerable to a variety of attacks when an SSO login is initiated from the Argo CD CLI or UI. The vulnerabilities are due to the use of insufficiently random values in parameters in Oauth2/OIDC login flows. In each case, using a relatively-predictable (time-based) seed in a non-cryptographically-secure pseudo-random number generator made the parameter less random than required by the relevant spec or by general best practices. In some cases, using too short a value made the entropy even less sufficient. The attacks on login flows which are meant to be mitigated by these parameters are difficult to accomplish but can have a high impact potentially granting an attacker admin access to Argo CD. Patches for this vulnerability has been released in the following Argo CD versions: v2.4.1, v2.3.5, v2.2.10 and v2.1.16. There are no known workarounds for this vulnerability.

Security readout for executives and security teams

Plain-English summary

Argo CD used insufficiently random values during OAuth2/OIDC SSO login flows. An attacker who can exploit this difficult condition could potentially gain high-impact access, including admin access to Argo CD. Fixed releases are available; the sources state there are no known workarounds.

Executive priority

Treat this as a high-priority patch for Argo CD because successful exploitation could affect deployment control for Kubernetes environments. Urgency is highest for production Argo CD instances with privileged access and SSO enabled.

Technical view

CVE-2022-31034 is a CWE-330 issue in Argo CD v0.11.0 and later vulnerable ranges. Time-seeded, non-cryptographic pseudo-random generation and short values weakened OAuth2/OIDC parameters used in CLI and UI SSO login flows. CVSS is 8.3, high, with high attack complexity and user interaction required.

Likely exposure

Exposure is likely where affected Argo CD versions are deployed and users initiate SSO login through the Argo CD CLI or UI. Affected ranges include versions before 2.1.16, 2.2.10, 2.3.5, and 2.4.1 across their respective release lines.

Exploitation context

The advisory describes exploitation as difficult but potentially high impact. The provided sources do not show known active exploitation, and the CVE is not listed as KEV in the supplied bundle.

Researcher notes

Focus review on OAuth2/OIDC login parameter generation in affected Argo CD versions. The source commit is relevant for understanding the cryptographic randomness fix. Avoid assuming exploitation in the wild; the supplied evidence does not support that claim.

Mitigation direction

  • Upgrade Argo CD to v2.4.1, v2.3.5, v2.2.10, v2.1.16, or later supported releases.
  • Prioritize Argo CD instances that use OAuth2/OIDC SSO login from CLI or UI.
  • If patching is delayed, check Argo project guidance; sources state no known workarounds.
  • Review Argo CD admin access and authentication logs during the remediation window.

Validation and detection

  • Inventory all Argo CD server versions across clusters and environments.
  • Confirm each instance is outside the affected version ranges listed in the advisory.
  • Identify instances using SSO login flows through the Argo CD CLI or UI.
  • Verify upgraded instances are running the intended patched release line.

Use of Insufficiently Random Values

Use of Insufficiently Random Values represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
