jQuery version 3.4.1 is vulnerable to cross-site-scripting


OTRS uses the JavaScript library jQuery in version 3.4.1. This version is vulnerable to cross-site-scripting (XSS).

The official fix for this issue changes more than 40 files in OTRS. Therefore, there is no workaround. Your OTRS installation must be updated to version 6.0.30.

ATTENTION: Please check if you have any files in your OTRS installation that have been changed by additional add-ons. In that case you MUST NOT update your OTRS. Please contact us instead.
