Description

Capgo (Cap-go/capgo) before 12.128.2 contains an information disclosure vulnerability in the Supabase PostgREST RPC function public.get_total_metrics(org_id), which is callable by the anon role using only the public sb_publishable_* key. An unauthenticated attacker can probe organization existence and leak sensitive usage metrics including MAU, bandwidth, and install counts by sending POST requests to /rest/v1/rpc/get_total_metrics with valid organization UUIDs.
