CVE-2026-63397 · GHSA-w757-xvvv-vgfw
- Affected
- npm @genql/cli < 6.3.4
- Fixed in
- 6.3.4· Vendor fix available
- Issue
- remorses/genql before version 6.3.4 allows an authenticated attacker with control of the GraphQL schema that is passed to genql to inject arbitrary JavaScript or TypeScript. The malicious code is injected into the generated schema.ts file and executes when the genql client is bundled and imported.
Recommended action: Upgrade to 6.3.4 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
