Tags in templates can be used to disclose sensitive information
An agent logged in to OTRS can disclose sensitive information by using tags in templates.
Upgrade to the latest available OTRS patch level (https://ftp.otrs.org/pub/otrs/).
As a workaround, you can replace the affected files (see below for download).
ATTENTION: Please check if any of these files have been changed in your OTRS installation by additional add-ons. In that case you MUST NOT simply overwrite the files with the ones provided below. Please contact us instead.
