CVE-2023-4476Public exploitNetwork attack vector

Script execution via unescaped lpr-search reflection

Published Sep 25, 2023 · Updated Apr 23, 2025

Reflected XSS in Plainware Locatoraid Store Locator before 3.9.24 allows remote attackers to execute scripts through lpr-search. The front-end search page returns the lpr-search parameter into HTML without sanitizing or output escaping, so crafted attribute text becomes executable markup. Exploitation requires an administrator or another logged-in high-privilege user to open the attacker-supplied URL; script execution then occurs in that user's browser context.
