About

The China National Vulnerability Database (CNVD) operates as the official vulnerability disclosure and threat intelligence platform for the People's Republic of China. Established to centralize security information sharing, CNVD serves as the primary repository for vulnerability data affecting Chinese organizations and infrastructure. The platform facilitates coordinated disclosure processes between security researchers, vendors, and government entities.

CNVD maintains comprehensive vulnerability records covering software applications, operating systems, network devices, and industrial control systems. The database assigns unique CNVD identifiers to reported vulnerabilities and provides detailed technical documentation including affected versions, impact assessments, and remediation guidance. Security researchers can submit vulnerability reports through established disclosure channels, enabling systematic evaluation and response coordination.

The platform distinguishes itself through its focus on vulnerabilities affecting Chinese-developed software and systems commonly deployed within mainland China. CNVD collaborates with domestic technology vendors to ensure timely patch development and distribution. The database also maintains relationships with international vulnerability coordination centers to facilitate cross-border threat intelligence sharing when appropriate.

Chinese government agencies, state-owned enterprises, and domestic technology companies rely on CNVD for authoritative vulnerability information. The platform serves critical infrastructure operators in sectors including telecommunications, energy, transportation, and financial services. Academic institutions and security research organizations also utilize CNVD data for threat analysis and defensive planning purposes.

Within the global cybersecurity landscape, CNVD represents China's commitment to structured vulnerability management and responsible disclosure practices. The database complements international efforts while addressing region-specific security concerns and regulatory requirements. Security teams operating in Chinese markets often reference CNVD alongside global databases to maintain comprehensive threat awareness and ensure compliance with local cybersecurity regulations.
