DRUPAL-CONTRIB-2026-048
No affected components available
The Formatter Field module provides a mechanism for specifying a formatter and formatter settings to be used for displaying a field, on a per-entity basis.
formatter_field stores some data as PHP-serialized strings. In some situations, malicious data can be written directly to the field. This can lead to an Object Injection vulnerability when the data are unserialized.
This vulnerability is mitigated by the fact that an attacker must have permission to edit a content entity with an attached formatter_field field. In addition, the core JSON:API module must be enabled with the option "Accept all JSON:API create, read, update, and delete operations", which is not the default, or the attacker needs some other way to edit field values directly.
