@grpc/grpc-js: In certain configurations, getAuthContext can return unauthorized certificates as though they were authorized

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...

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

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...

Server-generated Error Message Containing Sensitive Information

Overview @grpc/grpc-js is a gRPC Library for Node Affected versions of this package are vulnerable to Server-generated Error Message Containing Sensitive Information via the server-side RPC error handler in server.ts, which unconditionally includes the raw exception message in the gRPC status...

Improper Certificate Validation

Overview @grpc/grpc-js is a gRPC Library for Node Affected versions of this package are vulnerable to Improper Certificate Validation via getAuthContext in server-interceptors.ts and the TLS session handling in transport.ts, where the authorized property of a TLS socket is not checked before...

CVE-2026-101916

@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 th...

CVE-2026-101915

@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...

CVE-2026-101914

@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.13.1 and 1.14.1, the exact path method name matcher used by RBAC performs a prefix comparison instead of an equality comparison when case-insensitive matching is enabled. If one service...

CVE-2026-101916

The @grpc/grpc-js library (versions prior to 1.13.6 and 1.14.5 ) contains a vulnerability where the getAuthContext function fails to distinguish between authorized and unauthorized peer certificates. This occurs specifically when server credentials have requireClientCertificate set to false . If ...

CVE-2026-101915

The @grpc/grpc-js library (versions prior to 1.13.6 and 1.14.5 ) is vulnerable to sensitive information disclosure . When an application method handler throws an uncaught error, the server includes the resulting error message in the status message sent to the client. This allows an attacker to po...

@grpc/grpc-js: The exact path match matcher incorrectly only applies a prefix match for case-insensitive matches

Impact When using RBAC to apply authentication rules, the exact path method name matcher applies a prefix match instead of an exact match for case-insensitive matches. As a result, if a service has a method with a name that is a prefix of the name of a different method, and they have different...
