SA-CONTRIB-2015-040 – Webform prepopulate block – Cross Site Scripting (XSS)

Description

The module doesn’t sufficiently sanitize user supplied text when displaying the block, thereby exposing a Cross Site Scripting vulnerability.

This vulnerability is mitigated by the fact that an attacker must have a role with permission to create or edit nodes.
