Flag Lists – Moderately Critical – Cross Site Scripting – SA-CONTRIB-2016-051

Leave a comment

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.
