Recommendation: Monitor — no exploitation signal at the moment.

Capgo before 12.128.2 contains a scope escalation vulnerability in the POST /functions/v1/apikey endpoint that allows app-limited API keys to mint unrestricted keys by setting empty limits. Attackers with a compromised app-limited key can create an unrestricted key with org-wide access to resources like app listings and other protected endpoints.
