Description
Capgo before 12.128.2 contains a credential validation vulnerability in the POST /functions/v1/private/validate_password_compliance endpoint that is callable using only the public Supabase key without authentication. The endpoint is CORS-permissive with wildcard origin allowance and lacks rate limiting, enabling attackers to perform password spraying and credential stuffing attacks to compromise user accounts.
