   * Advisory ID: DRUPAL-SA-CONTRIB-2015-040
   * Project: Webform prepopulate block [1]     (third-party module)
   * Version: 7.x
   * Date: 2015-February-11
   * Security risk: 14/25 ( Moderately Critical)
     AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2]
   * Vulnerability: Cross Site Scripting

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

Webform prepopulate block module enables you to set a webform component to
display in a separated block.

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.

   * /A CVE identifier [3] will be requested, and added upon issuance, in
     accordance
            with Drupal Security Team processes./

prepopulate block [4] module, there is nothing you need to do.

-------- SOLUTION
