drupal/custom_formatters - SA-CONTRIB-2026-225
The Custom Formatters module allows users to easily create custom Field Formatters through an admin UI without writing a custom module.
The PHP formatter engine runs eval() to execute user-provided PHP code and allows arbitrary PHP execution on the site. The permissions UI gives no indication about this behavior.
