CVE-2026-101915— @grpc/grpc-js: The server transmits some error messages thrown by method handlers to the client in status messages

Quick assessment

Affected
grpc grpc-node
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

@grpc/grpc-js 是一个完全使用 JavaScript（而非 C++ 原生扩展）实现的 gRPC 核心功能库。在版本 1.13.6 和 1.14.5 之前，当应用程序的方法处理程序抛出一个未捕获的错误时，服务端会将该错误的错误消息包含在发送给客户端的状态消息中。这导致错误消息被直接传输给客户端，若该消息中包含敏感数据，则会引发敏感信息泄露漏洞。该问题已在版本 1.13.6 和 1.14.5 中修复。

Vulnerability Title
@grpc/grpc-js: The server transmits some error messages thrown by method handlers to the client in status messages
Source: CVE Program / CVE List V5
Vulnerability Description
@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.13.6 and 1.14.5, when an application method handler throws an uncaught error, the server includes its error message in the status message sent to the client. The thrown error message is transmitted to the client, causing sensitive information disclosure when the message contains sensitive data. This issue is fixed in versions 1.13.6 and 1.14.5.
