Capgo before 12.128.2 contains an information disclosure vulnerability in the GET /statistics/app/:app_id endpoint that allows app-limited API keys to distinguish existing sibling app IDs through differential error responses. Attackers can enumerate real app IDs outside their allowed scope by observing 500 PGRST116 errors for inaccessible apps versus 401 errors for nonexistent apps, breaking tenant isolation.
