Published Sep 26, 2024 · Updated Apr 8, 2026

Stored XSS in nitinmaurya12 WordPress Visitors 1.0 and earlier allows remote attackers to inject scripts through a spoofed HTTP header. The plugin stores an attacker-controlled header value without sufficient sanitization and renders it without escaping on the nm_vistior page. No authentication is required to plant the payload; script execution occurs when a user opens that visitor page.
