Statement

* This issue affects the version of python-django as shipped with Red Hat Gluster Storage 3 as it contains the vulnerable code. * This issue does not affect Red Hat Satellite 6, versions 6.3, 6.4 and 6.5, because its django component only returns content-type as JSON, which does not lead to cross site scripting. * This issue does not affect Red Hat Update Infrastructure 3 because it does not use any of the Widgets provided by python-django, including AdminURLFieldWidget. * This issue does not affect redhat-certification because it does not use AdminURLFieldWidget from python-django package.

Common Vulnerability Scoring System (CVSS) Score Details

Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

The following CVSS metrics and score provided are preliminary and subject to review.
