CVE-2017-6927 (opens in a new tab)How to fix?
Upgrade Debian:8 drupal7 to version 7.32-1+deb8u10 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream drupal7 package and not the drupal7 package as distributed by Debian.
See How to fix? for Debian:8 relevant fixed versions and status.
Drupal 8.4.x versions before 8.4.5 and Drupal 7.x versions before 7.57 has a Drupal.checkPlain() JavaScript function which is used to escape potentially dangerous text before outputting it to HTML (as JavaScript output does not typically go through Twig autoescaping). This function does not correctly handle all methods of injecting malicious HTML, leading to a cross-site scripting vulnerability under certain circumstances. The PHP functions which Drupal provides for HTML escaping are not affected.
