Versions 1.2.0 through 1.8.7, 2.0.0-rc1 through 2.14.19, 3.0.0-rc1 through 3.2.0-rc1, 3.1.7 and 3.0.18 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 complete API outage. This issue is fixed in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.\n\n## Affected\n\n- `argo_cd >= 1.2.0, <= 1.8.7`\n- `argo_cd >= 2.0.0, < 2.14.20`\n- `argo_cd >= 3.0.0, < 3.0.19`\n- `argo_cd >= 3.1.0, < 3.1.8`\n- `argo_cd = 3.2.0`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `argo_cd 3.1.8`","depth":"twilight","depthScore":41,"depthScoreParts":{"impact":41.3,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
