CVE-2024-0187Public exploitNetwork attack vector

Administrator-session script execution via unescaped generated URLs

Published Jan 16, 2024 · Updated May 22, 2025

Reflected XSS in Community by PeepSo before 6.3.1.2 allows remote attackers to execute scripts in an administrator's browser. Affected admin-page links pass attacker-controlled query parameters through add_query_arg and place generated URLs in HTML attributes without output escaping. Exploitation requires an administrator to follow a crafted link while the plugin's registration notice is displayed, exposing that session's accessible data and actions to injected script.
