{"id":"CVE-2026-40887","aliases":["GHSA-9pp3-53p2-ww9v"],"url":"https://o3.security/vulnerability/CVE-2026-40887","summary":"@vendure/core has a SQL Injection vulnerability","details":"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.","published":"2026-04-21T19:24:59.525Z","modified":"2026-08-07T11:31:18.536650752Z","cvss":{"score":9.1,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"@vendure/core","fixedVersion":"3.5.7"},{"ecosystem":"npm","name":"@vendure/core","fixedVersion":"3.6.2"},{"ecosystem":"npm","name":"@vendure/core","fixedVersion":"2.3.4"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40887.json"},{"type":"ADVISORY","url":"https://github.com/vendurehq/vendure/security/advisories/GHSA-9pp3-53p2-ww9v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40887"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T11:31:18.536650752Z"}}
