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

    @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 requireClientCertific…

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

    @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…

    @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-insensiti…

    gRPC-Go: Denial of Service (DoS) via crash due to missing `:authority` and `Host` headers in the xDS servers

    gRPC-Go is the Go language implementation of gRPC. Prior to 1.82.2 and 1.83.2, servers created with xds.NewGRPCServer() allow internal/transport/http2_server.go to accept an RPC containing neither the :authority header nor the Host header, while RouteAndProce…

  • High 8.7

    gRPC-Go: Heap Memory Exhaustion (OOM) via HTTP/2 DATA Frame Fragmentation

    gRPC-Go is the Go language implementation of gRPC. Prior to 1.83.1, internal/transport/transport.go stores each fragmented HTTP/2 DATA frame as a separate recvMsg in recvBuffer, so millions of one-byte frames can consume disproportionate heap memory even when…

  • Medium 6.3

    gRPC-Go: xDS RBAC HTTP Filter bypass via mixed-case Header Matching and gRFC A41 validation evasion

    gRPC-Go is the Go language implementation of gRPC. Prior to 1.83.1, the xDS RBAC HTTP filter in internal/xds/httpfilter/rbac/rbac.go does not lowercase header matcher names in normalizeHeaderMatcher even though incoming metadata keys are lowercase. A DENY pol…

    @grpc/grps-js: An incoming malformed compressed message can cause a client or server crash

    @grpc/grps-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4, an invalid incoming compressed message can cause a client or server process that uses @grpc/grpc-j…

    @grpc/grps-js: A malformed request can cause a server crash

    @grpc/grps-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.9.16, 1.10.12, 1.11.4, 1.12.7, 1.13.5, and 1.14.4, an invalid incoming HTTP/2 stream initiation can cause a server process created using @grpc/grpc-j…

    CVE-2026-33186 Public exploit

    gRPC-Go has an authorization bypass via missing leading slash in :path

    gRPC-Go is the Go language implementation of gRPC. Versions prior to 1.79.3 have an authorization bypass resulting from improper input validation of the HTTP/2 `:path` pseudo-header. The gRPC-Go server was too lenient in its routing logic, accepting requests …

    Denial of Service through Data corruption in gRPC-C++

    There exists a denial of service through Data corruption in gRPC-C++ - gRPC-C++ servers with transmit zero copy enabled through the channel arg GRPC_ARG_TCP_TX_ZEROCOPY_ENABLED can experience data corruption issues. The data sent by the application may be cor…

  • Medium 5.3

    @grpc/grpc-js can allocate memory for incoming messages well above configured limits

    @grpc/grps-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to versions 1.10.9, 1.9.15, and 1.8.22, there are two separate code paths in which memory can be allocated per message in excess of the `grpc.max_receive_…

    Denial of Service via reachable assertion in grpc-swift

    grpc-swift is the Swift language implementation of gRPC, a remote procedure call (RPC) framework. Prior to version 1.7.2, a grpc-swift server is vulnerable to a denial of service attack via a reachable assertion. This is due to incorrect logic when handling G…
