CVE-2022-3869Public exploitNetwork attack vector

Browser script execution via customermail reflection

Published Nov 5, 2022 · Updated May 5, 2025

Reflected XSS in Froxlor before 0.10.38.2 allows remote attackers to execute browser script through a crafted customermail query value. The public index.php error path inserts a validated customermail GET value into an HTML error message without output encoding. A victim must open the crafted request; the script runs in the Froxlor origin and can read or alter data exposed to that browser session.
