CVE-2022-35499Public exploitNetwork attack vector

Browser script execution via reflected URL parameter

Published Sep 4, 2026 · Updated Sep 4, 2026

Reflected XSS in Trimble TM4WEB 21.4.0.4 allows remote attackers to execute script in a victim's browser via a crafted bill-viewer URL. The external bill viewer copies an arbitrary URL parameter into its HTML response without neutralizing script content. Exploitation requires a user to follow the crafted link; the script runs in the TM4WEB origin and can read or modify browser-accessible data within that origin.
