Cross-site scripting (XSS) vulnerability in the Protected Node module 5.x before 5.x-1.4 and 6.x before 6.x-1.5, a module for Drupal, allows remote authenticated users with "administer site configuration" permissions to inject arbitrary web script or HTML via the Password page info field, which is not properly handled by the protected_node_enterpassword function in protected_node.module.
