CVE-2026-101914

The @grpc/grpc-js library (versions prior to 1.13.1 and 1.14.1 ) contains an authorization flaw where the exact path matcher used by RBAC performs a prefix comparison instead of an equality comparison when case-insensitive matching is enabled. This allows a request for a longer service method nam...

CVE-2026-101914 @grpc/grpc-js: The exact path match matcher incorrectly only applies a prefix match for case-insensitive matches

@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...
