Upgrade launder to version 1.7.1 or higher.
Overview
launder is an A sanitize module for the people. Built for ApostropheCMS.
Affected versions of this package are vulnerable to Improper Encoding or Escaping of Output via the linkHref field handling. An attacker can execute arbitrary JavaScript by supplying a javascript: URL in an image widget's link URL field and having it rendered on the page. This affects users who can edit content and allows an attacker to run a script in viewers’ browsers, exposing session data and enabling unauthorized actions on the affected site.
Workaround
Restrict who can edit or publish image widgets so untrusted users cannot set the Link to field to a javascript: URL; this prevents stored XSS from being published to pages viewed by others.
