grpc — Vulnerabilities & Security Advisories 4

gRPC serves as a high-performance RPC framework enabling efficient communication between microservices. Historically, vulnerabilities have included remote code execution, denial-of-service, and authentication bypass flaws, with four CVEs currently documented. The framework's use of HTTP/2 and Protocol Buffers introduces potential attack surfaces in header parsing and service method exposure. While no major incidents have been widely reported, security researchers have identified issues in implementations affecting multiple vendors. Its strict typing and contract-first design offer some inherent security benefits, but misconfigurations remain a common risk factor in production deployments.
