Capgo before 12.128.2 contains a scope isolation vulnerability in the POST /webhooks/test endpoint that allows app-scoped API keys to invoke org-scoped webhook operations. Attackers with app-scoped credentials can trigger signed outbound webhook deliveries for arbitrary organization webhooks outside their declared app boundary, bypassing the limited_to_apps authorization check.
