Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. 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.

GHSA-gpx4-37g2-c8pv — Argo CD Unauthenticated Remote DoS via malformed Azure DevOps git.push webhook

Affected: Go: github.com/argoproj/argo-cd/v2, Go: github.com/argoproj/argo-cd/v3

### Summary

In the default configuration, `webhook.azuredevops.username` and `webhook.azuredevops.password` not set, Argo CD’s /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.

### Details

```go case azuredevops.GitPushEvent: // util/webhook/webhook.go -- line ≈147 revision = ParseRevision(payload.Resource.RefUpdates[0].Name) // panics if slice empty change.shaAfter = ParseRevision(payload.Resource.RefUpdates[0].NewObjectID) change.shaBefore= ParseRevision(payload.Resource.RefUpdates[0].OldObjectID) touchedHead = payload.Resource.RefUpdates[0].Name == payload.Resource.Repository.DefaultBranch ```

If the attacker supplies "refUpdates": [], the slice has length 0.

The webhook code has no recover(), so the panic terminates the entire binary.

### PoC

payload-azure-empty.json: ```json { "eventType": "git.push", "resource": { "refUpdates": [], "repository": { "remoteUrl": "https://example.com/dummy", "defaultBranch": "refs/heads/master" } } } ```
