CVE-2023-54361Public exploitNetwork attack vector

Reflected XSS via unescaped filter_keyword output

Published Apr 9, 2026 · Updated Apr 9, 2026

Reflected XSS in Thinkery LLC IProperty 4.1.1 allows remote attackers to run scripts in a victim's browser through a crafted link. The all-properties-with-map view reflects the filter_keyword GET value into page markup without neutralizing an injected quote and event handler. Exploitation requires a victim to open the crafted URL or interact with the injected page element, after which the script runs in the site's browser origin and can access session data or act as that user.
