### Summary Unpatched Argo CD versions are vulnerable to malicious API requests which can crash the API server and cause denial of service to legitimate clients. With the default configuration, no `webhook.bitbucketserver.secret` set, Argo CD’s /api/webhook endpoint will crash the entire argocd-server process when it receives a Bitbucket-Server push event whose JSON field `repository.links.clone` is anything other than an array. A single unauthenticated curl request can push the control-plane into CrashLoopBackOff; repeating the request on each replica causes a complete outage of the API. ### Details ```go // webhook.go (Bitbucket-Server branch in affectedRevisionInfo) for _, l := range payload.Repository.Links["clone"].([]any) { // <- unsafe cast link := l.(map[string]any) ... } ``` If links.clone is a string, number, object, or null, the first type assertion panics: interface conversion: interface {} is string, not []interface {} The worker goroutine created by star...

### Summary A race condition in the repository credentials handler can cause the Argo CD server to panic and crash when concurrent operations are performed on the same repository URL. ### Details The vulnerability is located in numerous repository related handlers in the `util/db/repository_secrets.go` file. For example, in the `secretToRepoCred` function. The issue manifests as a concurrent map access panic: ``` concurrent map read and map write ... goroutine 1104 [running]: github.com/argoproj/argo-cd/v2/util/db.(*secretsRepositoryBackend).secretToRepoCred(0xc000e50ea8?, 0xc000c65540) /go/src/github.com/argoproj/argo-cd/util/db/repository_secrets.go:404 +0x31e ``` The race condition occurs due to: 1. Concurrent repository credential operations (create/update/delete) accessing the same map 2. Kubernetes informer re-syncs happening simultaneously 3. Background watchers updating the same secret data 4. No mutex protection for map access A valid API token with `repositories`...
