CVE-2026-40887

CVE-2026-40887 is a critical-severity vulnerability with a CVSS 3.x base score of 9.1. It is not currently listed as actively exploited by CISA, and its EPSS exploit-prediction score is low. The underlying weakness is classified as CWE-89.

Key facts

Description

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.
