Capgo before 12.128.2 contains an information disclosure vulnerability in the /private/validate_password_compliance endpoint that returns different error responses for malformed, non-existent, and existing organization IDs. Unauthenticated attackers can enumerate valid organization UUIDs by observing response status codes and error messages, allowing confirmation of organization existence.
