Matter — Vulnerabilities & Security Advisories 3

Matter is an open-source smart home connectivity protocol designed to unify device communication across ecosystems. Historically, it has faced vulnerabilities including remote code execution, cross-site scripting, and privilege escalation, primarily affecting device authentication and communication layers. While no major public incidents have been widely reported, the protocol's security model relies heavily on proper implementation by device manufacturers. The three documented CVEs highlight risks in device onboarding processes and network communication, emphasizing that security depends on consistent adherence to specifications across the diverse hardware ecosystem.
