Specifically, versions prior to 2.3.4, 3.5.7, and 3.6.2 are vulnerable in the Shop API. This vulnerability allows unauthenticated attackers to inject arbitrary SQL code by manipulating a query string parameter (likely \u003ccode\u003elanguageCode\u003c/code\u003e) that is then directly interpolated into a raw SQL expression. Exploitation does not require authentication, posing a significant risk to vulnerable Vendure instances. The vulnerability impacts all supported database backends, including PostgreSQL, MySQL/MariaDB, and SQLite.
