CVE-2023-54364Public exploitNetwork attack vector

Session-token theft via reflected filter parameters

Published Apr 9, 2026 · Updated Apr 9, 2026

Reflected XSS in HikaShop Business 4.2.0 through 4.7.4 allows remote attackers to execute script in a victim's browser. The product filter endpoint reflects crafted from_option, from_ctrl, from_task, or from_itemid GET values into its response without safely neutralizing script content. No authentication is required, but a victim must open a crafted URL; script execution can expose that victim's session tokens or login credentials.
