Six Proto6 Vulnerabilities in protobuf.js Expose Node.js Apps to RCE and DoS

Security researchers have discovered six vulnerabilities in protobuf.js, a widely-used JavaScript/TypeScript implementation of Protocol Buffers. These flaws could enable attackers to execute remote code execution (RCE) and denial-of-service (DoS) attacks against Node.js applications.
