description

Available evidence identifies Drupal core's Field UI module as affected. An unauthenticated attacker may be able to achieve code execution through interactions with contributed modules, although the exact module and configuration prerequisites are not established by the supplied evidence.

mitigation

Disable the Field UI module where it is not required and reduce public exposure of affected Drupal sites. Review enabled contributed modules and apply Drupal security updates when the applicable fixed release is identified.
