CVE-2022-46888Network attack vector

Browser script execution via unencoded request parameters

Published Jan 19, 2023 · Updated Apr 3, 2025

Reflected XSS in NexusPHP before 1.7.33 allows remote attackers to inject web script through six crafted request parameters. The affected endpoints place secret, q, query, text, or id values into generated pages without sufficient output neutralization, reflecting supplied HTML or script. Exploitation requires a user to open a crafted request; the script then runs in the NexusPHP origin and can access data available to that browser session.
