CVE-2026-67360Network attack vector

Cross-customer order data exposure via unchecked ownership

Published Aug 21, 2026 · Updated Aug 21, 2026

IDOR in J2Commerce J2Store allows remote authenticated users to copy another customer's order data into their session. In affected releases, the myprofile reOrder task validates login and CSRF state but loads a client-supplied order_id without confirming ownership. Exploitation requires another customer's order ID and exposes product selections, quantities, options, and address data while leaving the source order unchanged.
