CVE-2026-101914 · @grpc/grpc-js: The exact path match matcher incorrectly only applies a prefix match for case-insensitive matches
This page contains facts from public vulnerability sources. Check the original advisory before updating.
@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 method name prefixes another and the methods have different access rules, a request for the longer method can match the shorter method's rule and cause incorrect authorization. This issue is fixed in versions 1.13.1 and 1.14.1.
