▸Company Profile

Protobufjs is an open-source JavaScript library for encoding, decoding, and working with Protocol Buffers (protobuf), a data serialization format developed by Google. It is widely used in Node.js and browser environments for efficient data interchange in APIs, microservices, and real-time applications. Its cybersecurity relevance stems from potential vulnerabilities in serialization/deserialization logic that could lead to denial of service or remote code execution if not properly handled.
