Potential XSS vulnerability in Kitodo.Presentation

Impact

Kitodo.Presentation fails to properly encode URL parameters for output in HTML making it vulnerable to Cross Site Scripting (XSS). Only sites using the ListView, Navigation or PageView plugins are affected.

It also includes jQuery 3.4.1 which is known to be vulnerable against Cross Site Scripting, although there is currently no known way to exploit this in Kitodo.Presentation.

Patches

An updated version of Kitodo.Presentation is available on GitHub, Packagist and in the TYPO3 Extension Repository. Users are advised to update as soon as possible.

The issue was also fixed in release 2.3.1 of the 2.x branch, although it is generally not recommended to run this branch since it depends on an outdated TYPO3 version.
