Vendure is an open-source headless commerce platform. Starting in version 1.7.4 and prior to versions 2.3.4, 3.5.7, and 3.6.2, an unauthenticated SQL injection vulnerability exists in the Vendure Shop API. A user-controlled query string parameter is interpolated directly into a raw SQL expression without parameterization or validation, allowing an attacker to execute arbitrary SQL against the database. This affects all supported database backends (PostgreSQL, MySQL/MariaDB, SQLite). The Admin API is also affected, though exploitation there requires authentication. Versions 2.3.4, 3.5.7, and 3.6.2 contain a patch. For those who are unable to upgrade immediately, Vendure has made a hotfix available that uses `RequestContextService.getLanguageCode` to validate the `languageCode` input at the boundary. This blocks injection payloads before they can reach any query. The hotfix replaces the existing `getLanguageCode` method in `packages/core/src/service/helpers/request-context/request-context.service.ts`. Invalid values are silently dropped and the channel's default language is used instead. The patched versions additionally convert the vulnerable SQL interpolation to a parameterized query as defense in depth.

GHSA-9pp3-53p2-ww9v — @vendure/core has a SQL Injection vulnerability

Affected: npm: @vendure/core

## Summary

An unauthenticated SQL injection vulnerability exists in the Vendure Shop API. A user-controlled query string parameter is interpolated directly into a raw SQL expression without parameterization or validation, allowing an attacker to execute arbitrary SQL against the database. This affects all supported database backends (PostgreSQL, MySQL/MariaDB, SQLite).

The Admin API is also affected, though exploitation there requires authentication.

## Affected versions

- `@vendure/core` < 2.3.4 - `@vendure/core` >= 3.0.0, < 3.5.7 - `@vendure/core` >= 3.6.0, < 3.6.2

Note: versions 2.3.4 and above in the 2.x line are patched. There were no 2.4.x or 2.x releases between 2.3.x and 3.0.0.

## Patched versions

- `@vendure/core` 2.3.4 - `@vendure/core` 3.5.7 - `@vendure/core` 3.6.2

## Details

In `ProductService.findOneBySlug`, the request context's `languageCode` value is interpolated into a SQL `CASE` expression via a JavaScript template literal:

```ts .addSelect( `CASE translation.languageCode WHEN '${ctx.languageCode}' THEN 2 WHEN '${ctx.channel.defaultLanguageCode}' THEN 1 ELSE 0 END`, 'sort_order', ) ```

TypeORM has no opportunity to parameterize this value because it is embedded directly into the SQL string before being passed to the query builder.

The `languageCode` value can originate from the HTTP query string and is set on the request context for every incoming API request. The value is cast to the `LanguageCode` TypeScript type at compile time, but n…
