Technical details

A SQL injection vulnerability exists in ProductService.findOneBySlug where the languageCode value from the HTTP request context is interpolated directly into a raw SQL CASE expression using a JavaScript template literal, bypassing TypeORM's parameterization. The languageCode originates from the query string and is cast to a TypeScript type at compile time but receives no runtime validation, allowing an attacker to inject SQL syntax. An unauthenticated attacker can append a crafted languageCode parameter to any Shop API request to execute arbitrary SQL against PostgreSQL, MySQL/MariaDB, or SQLite backends. The vulnerability has been patched in versions 2.3.4, 3.5.7, and 3.6.2 by adding input validation and converting the interpolation to a parameterized query.
