CVE-2026-76564Network attack vector

Stored XSS via User-Agent header

Published Aug 20, 2026 · Updated Aug 21, 2026

Stored XSS in Admin Order View in Phoca Phoca Cart 5.0.0 through 6.1.7 allows remote attackers to execute script via a User-Agent header. Published records indicate that the component stores the request User-Agent with order data and later renders it in the administrative order view without neutralizing script content. Exploitation requires an administrator to open a poisoned order record, after which the payload runs in that browser context and can act with the administrator's session.
