DescriptionGitHub Advisory

OpenSTAManager is an open source management software for technical assistance and invoicing. OpenSTAManager v2.9.8 and earlier contains Reflected XSS vulnerabilities in invoice/order/contract modification modals.

This allows an attacker to break out of the attribute context and inject arbitrary HTML/JavaScript.
