CVE-2026-15920

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.
