Moderately critical 13 ∕ 25 AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All
Vulnerability: 
Cross site scripting
Affected versions: 
<5.11.0
Description:

The module doesn't sufficiently filter user input under in the scenario when a webform is edited, namely the message related to character min/max counter does not undergo sufficient filtering and thus allows execution of JavaScript code through it.

Solution: 

Install the latest version:
