Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Drupal core versions 8.9.0 up to but not including 10.6.19, 11.0.0 up to 11.3.19, 11.4.0 up to 11.4.10, and 12.0.0-alpha1 up to 12.0.0-beta2 (Packagist drupal/core) have a remote code execution vulnerability in the Field UI module. The source says core alone is not directly exploitable, but contributed modules and custom code can expose it, and at least one known path does not require authentication. Upgrade to 10.6.19, 11.3.19, 11.4.10, or 12.0.0-beta2. Until then, the source suggests uninstalling the core Field UI module (field_ui) as a mitigation.
