Maxlength - Moderately critical - Cross Site Scripting - SA-CONTRIB-2019-073

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".

Install the latest version:

• If you use the Maxlength module for Drupal 7.x, upgrade to Maxlength 7.x-3.3

Also see the Maxlength project page.
