Technical details
A scope escalation vulnerability exists in Capgo's 'POST /functions/v1/apikey' endpoint due to insufficient validation of the caller's existing permissions. The backend logic in 'supabase/functions/_backend/public/apikey/post.ts' only blocked key creation if the caller's key had 'limited_to_orgs' defined, failing to check for 'limited_to_apps' restrictions. A remote attacker with a valid app-limited API key can send a request with empty limit arrays to generate a new key with 'mode: all' and organization-wide access. This allows the attacker to bypass least-privilege controls and access protected endpoints such as '/app' to list all organizational resources. The issue is fixed in version 12.128.2 by ensuring all restricted keys are blocked from minting broader-scope keys.
