For versions 2.9.0-rc1 through 2.14.19, 3.0.0-rc1 through 3.2.0-rc1, 3.1.6 and 3.0.17, when the webhook.azuredevops.username and webhook.azuredevops.password are not set in the default configuration, the /api/webhook endpoint crashes the entire argocd-server process when it receives an Azure DevOps Push event whose JSON array resource.refUpdates is empty. The slice index [0] is accessed without a length check, causing an index-out-of-range panic. A single unauthenticated HTTP POST is enough to kill the process. This issue is resolved in versions 2.14.20, 3.2.0-rc2, 3.1.8 and 3.0.19.\n\n## Affected\n\n- `argo_cd >= 2.9.0, < 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":43,"depthScoreParts":{"impact":41.3,"likelihood":1.8,"exploitation":0,"ransomware":0},"changes":[]}
