CVE-2017-12794 (opens in a new tab)How to fix?
Upgrade Echo:latest python-django to version 1:1.11.5-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream python-django package and not the python-django package as distributed by Echo.
See How to fix? for Echo:latest relevant fixed versions and status.
In Django 1.10.x before 1.10.8 and 1.11.x before 1.11.5, HTML autoescaping was disabled in a portion of the template for the technical 500 debug page. Given the right circumstances, this allowed a cross-site scripting attack. This vulnerability shouldn't affect most production sites since you shouldn't run with "DEBUG = True" (which makes this page accessible) in your production settings.
