Prior to 3.7.14 and 4.1.10, a vulnerability was identified in the Twig sandbox security policy that allowed database write operations when cms.safe_mode is enabled. Backend users with Developer permissions could use Twig template markup to execute insert, update, and delete operations on any database table through the query builder, which is included in the sandbox allow-list. This vulnerability is fixed in 3.7.14 and 4.1.10.
