CVE-2023-3228Network attack vector

Unauthorized cart changes via unchecked add-on selection

Published Jun 14, 2023 · Updated Jan 2, 2025

Business logic errors in FOSSBilling before 0.5.0 allow remote authenticated users to add unauthorized products to a shopping cart. The guest Cart API accepts add-on products independently and trusts submitted add-on identifiers without checking the selected product's configured add-on list. A valid low-privilege session and suitable catalog records are required, and the bounded consequence is unauthorized alteration of cart contents.
