CVE-2025-49046Network attack vector

Script execution via unescaped reflected input

Published Jan 22, 2026 · Updated Jan 22, 2026

Reflected XSS in Lambert Group xPromoter 1.3.4 and earlier allows remote attackers to execute scripts through a crafted link. The top_bar_promoter component reflects user-controlled input into generated HTML without sufficient sanitization or output escaping; the parameter is undisclosed. Exploitation requires a victim to follow the link, after which the script runs in that user's browser context and accesses or alters page-accessible data.
