Multiple Cross-Site Scripting (XSS) issues were discovered in EPESI 1.8.1.1. The vulnerabilities exist due to insufficient filtration of user-supplied data (cid, value, element, mode, tab, form_name, id) passed to the EPESI-master/modules/Utils/RecordBrowser/grid.php URL. An attacker could execute arbitrary HTML and script code in a browser in the context of the vulnerable website.
