@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, getAuthContext does not distinguish authorized from unauthorized peer certificates when server credentials set requireClientCertificate to false. When applications use the returned authentication context, they can treat an unauthorized certificate as authorized, causing improper authentication. @grpc/grpc-js-xds can reach this condition when RBAC authentication is enabled in affected configurations. This issue is fixed in version 1.14.5 and 1.13.6.

 https://vulnerability.circl.lu/vuln/ghsa-m9gg-hp2v-232j GHSA-m9gg-hp2v-232j — @grpc/grpc-js: In certain configurations, getAuthContext can return unauthorized certificates as though they were autho… 2026-10-01T15:40:54.486923+00:00

Affected: npm: @grpc/grpc-js

### Impact When server credentials are created with the `requireClientCertificate` option set to `false`, `getAuthContext` does not distinguish between authorized and unauthorized certificates in its return value. This can create improper authentication vulnerabilities for `@grpc/grpc-js` users who use the result of `getAuthContext` for authentication.

In particular, `@grpc/grpc-js-xds` can both set the `requireClientCertificate` option to `false` and use the return value of `getAuthContext` for RBAC authentication in some configurations.

### Patches

This vulenrability is fixed in 1.13.6 and 1.14.5.

### Workarounds `@grpc/grpc-js` users using `getAuthContext` this way can avoid this problem by setting `requireClientCertificate` to `true`. `@grpc/grpc-js-xds` users using RBAC can avoid this by setting the `require_client_certificate` field to `true` in the DownstreamTlsContext in the xDS configuration.
