No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Capgo before 12.128.2 contains an authorization bypass vulnerability in its public API key management handlers (get/put/delete/post). API keys created with mode=all but restricted to a single app via limited_to_apps are only checked for limited_to_orgs and not for limited_to_apps, so an app-scoped key can enumerate, update, and delete sibling API keys belonging to the same account that are outside its declared app scope, enabling tampering with account-level credentials.
