Linux Distros Unpatched Vulnerability : CVE-2026-15920

medium Nessus Plugin ID 332076

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - 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.
 (CVE-2026-15920)

Note that Nessus relies on the presence of the package as reported by the vendor.
