Cap-go capgo before 12.128.2 contains an authorization bypass in several Supabase PostgREST RPC functions (getappmetrics, getglobalmetrics, gettotalmetrics) that are granted to the anon role without enforcing org membership or permission checks. An unauthenticated attacker using only the public Supabase API key (sbpublishable*) can query arbitrary org_id values to disclose cross-tenant usage telemetry (MAU, bandwidth, installs, gets), enumerate app IDs for a target org, and determine org existence via an oracle (valid org returns metrics, invalid returns []).
