CVE-2026-103036
NVD: oRPC is a tool that helps build APIs that are end-to-end type-safe and adhere to OpenAPI standards. NVD: Prior to 1.14.9, the @orpc/json-schema SmartCoercionPlugin uses JsonSchemaCoercer to collect object properties in a plain object and to resolve schema.properties entries through the prototype chain. NVD: A remote client that can reach a procedure with an object input schema can supply __proto__ to replace the prototype of the single coerced request object, or supply Object.prototype member names such as constructor and toString so inherited values are treated...
