Remote, unauthenticated, single-request read using a public key gives AV:N/AC:L/PR:N/UI:N; only confidentiality of business data is affected, so C:H with I:N/A:N and unchanged scope.

Lifecycle Timeline
2DescriptionCVE.org
Capgo before 12.128.2 contains an information disclosure vulnerability in the Supabase PostgREST global_stats endpoint that allows unauthenticated attackers to read sensitive financial and operational metrics using only the public apikey. Remote attackers can query the /rest/v1/global_stats endpoint to expose MRR, total revenue, plan-tier revenue breakdown, customer counts, and operational telemetry.
AnalysisAI
Unauthenticated information disclosure in Capgo before 12.128.2 exposes confidential business metrics through the Supabase PostgREST /rest/v1/global_stats endpoint, which lacks row-level security enforcement. Any remote party holding only the public (anon) Supabase apikey - a value embedded in Capgo client apps and therefore trivially obtainable - can read MRR, total and plan-tier revenue, customer counts, and operational telemetry. Reported by VulnCheck via a GitHub security advisory; no public exploit code or active exploitation has been identified at time of analysis, though the CVSS 4.0 score of 8.7 reflects high confidentiality impact with no barriers to access.
Technical ContextAI
Capgo is a live/over-the-air update platform for Capacitor (Ionic) mobile applications, and it uses Supabase - a hosted Postgres backend - with PostgREST automatically exposing database tables as REST endpoints. In this architecture, the 'anon' apikey is intentionally public and shipped inside client apps; access control is meant to be enforced by Postgres Row-Level Security (RLS) policies rather than by keeping the key secret. The root cause maps to CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor): the global_stats table/view was reachable through PostgREST without an RLS policy restricting it to privileged roles, so presenting the anon key alone returned aggregate financial and operational data. The single affected product per the CPE (cpe:2.3:a:capgo:capgo:*) is the Capgo application/backend itself.
RemediationAI
Vendor-released patch: upgrade to Capgo 12.128.2 or later, which is the primary and authoritative fix per the GitHub advisory GHSA-73rv-fpp7-r3r4 (https://github.com/Cap-go/capgo/security/advisories/GHSA-73rv-fpp7-r3r4). If immediate upgrade is not possible, apply compensating controls at the Supabase layer: add or correct a Row-Level Security policy on the global_stats table/view to deny the 'anon' role (revoking the anon/public grant so PostgREST returns no rows), or drop the endpoint's exposure by removing global_stats from the exposed PostgREST schema - both eliminate the leak with the side effect of breaking any legitimate client feature that reads those aggregate stats. As a stopgap you can also restrict network access to the /rest/v1/global_stats path at a proxy/WAF, though this is weaker since the anon key is otherwise valid for other endpoints. Refer to the VulnCheck advisory (https://www.vulncheck.com/advisories/capgo-unauthenticated-information-disclosure-via-postgrest-global-stats-endpoint) for confirmation of scope.
