Published Dec 16, 2025 CVSS 4.0 · 8.5 High EPSS < 1% KEV · Not listed
Description
tRPC allows users to build and consume fully typesafe APIs without schemas or code generation. Starting in version 10.27.0 and prior to versions 10.45.3 and 11.8.0, a A prototype pollution vulnerability exists in `@trpc/server`'s `formDataToObject` function, which is used by the Next.js App Router adapter.
