CVE-2025-1511Network attack vector

Reflected script execution via unescaped search parameter

Published Feb 28, 2025 · Updated Apr 8, 2026

Reflected XSS in WPEverest User Registration & Membership 4.0.4 and earlier allows remote attackers to execute scripts via s. The membership administration list table places the s search parameter into its search-results heading without adequate sanitization or output escaping. Exploitation requires a targeted user to follow a crafted link, after which the injected script runs in that user’s browser context.
