CVE-2026-56082 Details
Description
Capgo (Cap-go/capgo) before 12.128.2 contains an improper access control vulnerability in the SECURITY DEFINER PostgREST RPC function public.record_build_time, which is granted to the anon role and callable with only the public Supabase publishable (sb_publishable_*) anon key. An unauthenticated attacker can insert rows into public.build_logs for arbitrary organizations and, because the function uses ON CONFLICT (build_id, org_id) DO UPDATE, can overwrite existing usage/billing records by reusing the same build_id for a target org. This enables cross-tenant tampering of billing build logs and financial-impact denial of service by inflating billable build time.
An improper access control vulnerability has been identified in Capgo versions prior to 12.128.2. The issue resides in the SECURITY DEFINER PostgREST RPC function 'public.record_build_time', which is accessible to the anon role via the public Supabase publishable anon key. This vulnerability allows an unauthenticated attacker to insert and update rows in the 'public.build_logs' table for any organization. The function's implementation, which uses 'ON CONFLICT (build_id, org_id) DO UPDATE', enables overwriting of existing billing records by reusing the same build_id for a target organization. Consequently, this vulnerability facilitates cross-tenant manipulation of billing logs and could lead to a financial-impact denial-of-service by inflating billable build time.
Users are advised to update to Capgo version 12.128.2 or later, where this vulnerability has been patched.
