Cap-go capgo (capgo-backend) before 12.128.12 contains an unauthenticated denial-of-service vulnerability arising from the audit logs table's Row-Level Security (RLS) policy when accessed via the Supabase PostgREST API. Because the PostgreSQL query planner executes costly logic before RLS rejection, unfiltered queries to the public.audit logs endpoint using the public anon key consistently trigger statement timeouts (PostgREST error 57014). Under concurrency, this exhausts database resources and causes cascading HTTP 500 failures on unrelated endpoints (e.g. /orgs), resulting in an application-layer denial of service.
