Summary
An issue was discovered in Django 5.2 before 5.2.17 and 6.0 before 6.0.8. `django.contrib.admin.utils.display_for_field()` renders `URLField` values as clickable links in the admin without validating the URL. A value stored with an unsafe scheme is displayed as a link on changelist and read-only admin pages, which allows cross-site scripting against staff users who click the link. Exploitation requires the unsafe value to already be stored in the database. `URLField` validation through a `ModelForm` or the admin rejects unsafe schemes, so this affects applications that persist `URLField` data without running model validation, for example through direct queryset writes, deserialization, or bulk import of untrusted input. Django would like to thank Egor Saltykov for reporting this issue.
