CVE-2026-73840OpenChoreo 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.
