Description The issue is related to reflected Cross-Site Scripting (XSS) that allows execution of arbitrary javascript code on a victim's browser. This occurs because the error page contents are not properly escaped.

Recommendations For Shuup versions 1.6.0 through 2.10.8, ensure that error page contents are properly escaped to prevent the execution of arbitrary javascript code.
