| Package | Affected versions | Patched versions |
|---|---|---|
| @vendure/core | ≥ 1.7.4, < 2.3.4≥ 3.0.0, < 3.5.7≥ 3.6.0, < 3.6.2 | 2.3.43.5.73.6.2 |
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.
@vendure/core < 2.3.4@vendure/core >= 3.0.0, < 3.5.7@vendure/core >= 3.6.0, < 3.6.2Note: 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.
@vendure/core 2.3.4@vendure/core 3.5.7@vendure/core 3.6.2In ProductService.findOneBySlug, the request context's languageCode value is interpolated into a SQL CASE expression via a JavaScript template literal:
.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 no runtime validation is performed -- the raw query string value is used as-is.
An unauthenticated attacker can append a crafted languageCode query parameter to any Shop API request to inject arbitrary SQL into the query. No user interaction is required. The vulnerable endpoint is exposed on every default Vendure installation.
Upgrade to a patched version immediately.
If you cannot upgrade right away, apply the following hotfix to RequestContextService.getLanguageCode to validate the languageCode input at the boundary. This blocks injection payloads before they can reach any query:
private getLanguageCode(req: Request, channel: Channel): LanguageCode | undefined {
const queryLanguageCode = req.query?.languageCode as string | undefined;
const isValidFormat = queryLanguageCode && /^[a-zA-Z0-9_-]+$/.test(queryLanguageCode);
return (
(isValidFormat ? (queryLanguageCode as LanguageCode) : undefined) ??
channel.defaultLanguageCode ??
this.configService.defaultLanguageCode
);
}
This 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.
