CVE-2026-108696
CoreShop through 1.5.5 contains an authorization bypass vulnerability in the OrderController that allows authenticated customers to act on other customers' orders by supplying user-controlled ids.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
