Technical details

An unauthenticated SQL injection vulnerability exists in Gridbox versions before 2.20.4.2, where the sort-by URL parameter on store product list pages is passed to GridboxHelper::getBlogPosts() without proper validation. The parameter is prefixed with a table alias and directly inserted into an ORDER BY clause, allowing an attacker to inject arbitrary SQL when the parameter value does not match known sorting keys.
