Improper Check or Handling of Exceptional Conditions

CVE-2025-59531

High
7.5/10

Summary

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. In versions 1.2.0-rc1 through 1.8.7, 2.0.0-rc1 through 2.14.19, 3.0.0-rc1 through 3.0.18, 3.1.0 through 3.1.7 and 3.2.0-rc0 are vulnerable to malicious API requests, which can crash the API server and cause denial of service to legitimate clients. Without a configured webhook.bitbucketserver.secret, Argo CD's /api/webhook endpoint crashes when receiving a malformed Bitbucket Server payload (non-array repository.links.clone field). A single unauthenticated request triggers CrashLoopBackOff, and targeting all replicas causes a complete API outage. This issue is fixed in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.
