CVE-2023-2743Public exploitNetwork attack vector

Administrator-targeted script execution via employee_name reflection

Published Jun 27, 2023 · Updated May 5, 2025

Reflected XSS in WP ERP before 1.12.4 allows remote attackers to execute scripts in an administrator's browser via employee_name. The leave-request filter page returns employee_name in HTML without sanitizing the parameter or escaping its output context. Exploitation requires an administrator to be signed in, open a crafted URL, and click Filter Leave Requests, after which attacker-supplied script runs with that browser session's access.
