OpenChoreo is a complete, open-source developer platform for Kubernetes. Prior to 1.0.3, 1.1.3, and 1.2.0-rc.2, the POST /api/v1alpha1/autobuild endpoint in internal/openchoreo-api/api/handlers/webhook_handler.go selected a webhook provider from caller-controlled X-Event-Key, accepted Bitbucket requests without HMAC-SHA256 in X-Hub-Signature or a configured bitbucket-secret, and allowed unauthenticated build triggers for components matched by repository URL and branch, including cross-provider triggers using attacker-supplied commit SHAs. This issue is fixed in versions 1.0.3, 1.1.3, and 1.2.0-rc.2.

Affected: Go: github.com/openchoreo/openchoreo

## Summary The OpenChoreo autobuild webhook endpoint (`POST /api/v1alpha1/autobuild`) selected the git provider used to authenticate an incoming webhook from a client-supplied request header rather than from the target component's configuration, and its Bitbucket provider accepted requests without a valid signature. A caller could set the `X-Event-Key` header to be treated as a Bitbucket webhook, bypassing the HMAC secret that otherwise protects GitHub and GitLab webhooks, and trigger a component build without authenticating.

## Impact An attacker who can reach the autobuild webhook endpoint and knows the repository URL and branch configured for an auto-build component can trigger a build for that component without authenticating — including components configured for GitHub or GitLab, since the provider used or verification is chosen by the caller rather than by the component's configuration. The triggered build runs against a commit SHA supplied by the attacker, and the component lookup is not scoped to a tenant or namespace, so any auto-build component across the cluster matching the given repository and branch is affected. This can result in unauthorized builds — and, where auto-deploy is configured, unauthorized deployment of attacker-influenced code — and can be used to exhaust build resources through repeated unauthenticated triggering.

The exposure applies to any component with `spec.autoBuild: true`, regardless of which git provider it declares, wherever the autobu…
