capnproto — Vulnerabilities & Security Advisories 4

Capnproto serves as a high-performance serialization system designed for low-latency data exchange across networks, commonly used in distributed systems and real-time applications. Historically, its vulnerabilities have primarily centered on remote code execution (RCE) and denial-of-service (DoS) flaws, often stemming from buffer handling and parsing issues. While no major public incidents have been widely documented, the four recorded CVEs highlight risks in memory safety and input validation. The system's binary protocol reduces certain attack surfaces compared to text-based alternatives, but its complex parsing logic remains a potential source of exploitation, particularly in untrusted environments.
