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

Exploitation and risk

CISA KEV lists vulnerabilities known to be exploited. FIRST EPSS estimates the likelihood of exploitation in the next 30 days. An unavailable score does not mean zero risk.

Which CVEs have scores here?

This view includes predictions for CVE identifiers explicitly listed in public NuGet advisories. Microsoft release pages have their own prediction coverage. Check source status for the scope and latest checks.

No exploitation or prediction data is available here for these CVEs. This does not mean they are safe or unlikely to be exploited.

cve-program · CVE-2026-101915

Published

@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.

### Impact If an application method handler crashes, the error message is included in the status message sent to the client. This can leak to the client any sensitive data that may be included in the error message. This impacts anyone using `@grpc/grpc-js` to run servers. ### Patches This vulnerability is fixed in 1.13.6 and 1.14.5. ### Workarounds This can be avoided by using a top-level error handler in method handlers to strip out sensitive error information.
