CVE-2025-40980Network attack vector

Session-cookie theft via unvalidated product names

Published Jul 31, 2025 · Updated Jul 31, 2025

Stored cross-site scripting in Ultimate Fosters UltimatePOS 6.4 allows remote authenticated users to steal session cookies via a product name. The product edit handler accepts the POST name parameter at /products/<PRODUCT_ID>/edit without proper validation and stores it for later rendering. Exploitation requires low-privileged product-edit access and a second authenticated user's browser to render the stored name, exposing that user's session cookie.
