NewCVE-2025-48383 (opens in a new tab)How to fix?
Upgrade django-select2 to version 8.4.1 or higher.
Overview
django-select2 is a Django integration of Select2.
Affected versions of this package are vulnerable to Transmission of Private Resources into a New Sphere ('Resource Leak') via a HeavySelect2Mixin class in forms.py. An attacker can access restricted data by exploiting the reuse of widget instances across different requests. This is limited to use cases where instances of widget classes are created during app loading and not during a request.
Workaround
This vulnerability can be mitigated by passing the widget class instead of an instance in the form definitions.
