Summary

Workbench, a suite of tools for administrators and developers to interact with Salesforce.com organizations via the Force.com APIs, prior to 65.0.0 contains a reflected cross-site scripting vulnerability via the footerScripts parameter, which does not sanitize user-supplied input before rendering it in the page response. Improper neutralization of input during web page generation ('cross-site scripting') vulnerability in Workbench allows XSS Targeting Error Pages.
