Summary

The Shield module for Drupal does not properly restrict excessive authentication attempts, enabling brute force attacks. This affects versions from 0.0.0 to 1.9.0.

Risk Assessment

Attackers can repeatedly guess passwords without restriction, increasing the risk of account takeover. This may lead to unauthorized access to the administrative panel.
