CVE-2019-20516Public exploitNetwork attack vector

Browser script execution via unescaped blog path

Published Mar 19, 2020 · Updated Aug 5, 2024

Reflected XSS in ERPNext 11.1.47 allows remote attackers to execute browser script through crafted PATH_INFO on the blog route. The blog route inserts the attacker-controlled trailing path segment into an HTML attribute without neutralizing quotation marks or event-handler syntax. A victim must open the crafted URL; the injected script then runs in the ERPNext origin with access to information available to that browser session.
