Company Profile
MessagePack for C# is an open-source, high-performance binary serialization library developed by Yoshifumi Kawai (neuecc) for the .NET ecosystem. It implements the MessagePack serialization format, offering faster and more compact data interchange compared to JSON, and is widely used in performance-critical applications such as real-time systems and microservices. Its cybersecurity relevance stems from its role in data serialization, where vulnerabilities in deserialization can lead to remote code execution or denial of service, as reflected in its tracked CVEs.
