Description
Capgo before 12.128.2 contains an authorization bypass vulnerability in the public.upsert_version_meta SECURITY DEFINER function exposed via PostgREST RPC, allowing unauthenticated attackers to insert arbitrary rows into version_meta for any app_id. Attackers can exploit this by calling the RPC endpoint with a public anon key to poison storage metrics, causing persistent false data in dashboards and triggering incorrect alerts across victim applications.
