Project: Maxlength [1]
Date: 2019-October-09
Security risk: *Moderately critical* 13∕25
AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross Site Scripting

Description: 
This module enables you to set a maximum length allowed on text fields and
indicate how many characters are left.

The module doesn't sufficiently filter strings leading to a Cross Site
Scripting (XSS) vulnerability.

This vulnerability is mitigated by the fact the malicious script will not be
triggered in the browser of UID 1 nor any user with "Bypass maxlength
setting".

Solution: 
Install the latest version:

  * If you use the Maxlength module for Drupal 7.x, upgrade to Maxlength
    7.x-3.3 [3]

Also see the Maxlength [4] project page.
