CVE-2025-52169Public exploitNetwork attack vector

Browser-session compromise via unencoded reflected input

Published Jul 18, 2025 · Updated Jul 5, 2026

Reflected XSS in Agorum core open 11.9.1.3-1857 allows remote attackers to execute scripts in a victim's browser through a crafted URL. BeginSSOLogin.jsp reflects the userName parameter into executable page output without adequate sanitization or context-sensitive encoding, and numerous other JSP endpoints exhibit the same behavior. A victim must open the crafted request, after which attacker-controlled JavaScript runs in that victim's session context and can access or alter content exposed to the page.
