   * Advisory ID: DRUPAL-SA-CONTRIB-2016-051
   * Project: Flag Lists [1]     (third-party module)
   * Version: 7.x
   * Date: 2016-September-07
   * Security risk: 14/25 ( Moderately Critical)
     AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2]
   * Vulnerability: Cross Site Scripting

-------- DESCRIPTION
---------------------------------------------------------

This module enables regular users to create unlimited private flags called
lists.

The flag_lists module doesn't sufficiently filter the output when applying
token strings to flag_lists links leading to a persistent Cross Site
Scripting (XSS) attack.

This vulnerability is mitigated by the fact that an attacker must have a role
with the "Create flag lists" permission.

     accordance with Drupal Security Team processes./
