Vulnerabilities must be reported per regulations; no details, exploit tools, or disclosure to foreign entities before patching

No cost involved. Simply report the vulnerability to the product vendor or an official platform. Until the vendor releases a patch, no details or verification code should be disclosed.

These regulations govern three main groups: domestic network product vendors, network operators, and any organizations or individuals involved in discovering, collecting, or publishing vulnerability information. No entity may use vulnerabilities to compromise network security, nor may they illegally collect, sell, or distribute such information. Five additional rules apply to public disclosure: first, nothing may be released before a vendor provides a patch; second, no details about vulnerabilities in active networks or systems may be published; third, no exaggerated claims about risks or malicious exploitation attempts may be made; fourth, no tools or programs designed for malicious exploitation may be released; and fifth, any disclosure must include remediation steps. Unreported vulnerabilities must also not be shared with foreign entities. The regulations encourage reporting to four official platforms: the Ministry of Industry and Information Technology’s Cybersecurity Threat and Vulnerability Information Sharing Platform; the National Cybersecurity Information Notification Center’s Vulnerability Platform; the National Computer Network Emergency Response Technical Team/Coordination Center of China’s Vulnerability Platform; and the China Information Security Evaluation Center’s Vulnerability Database. Violators may face penalties ranging from fines of 10,000 to 100,000 RMB, suspension of services, revocation of licenses or business licenses, and even criminal liability for responsible personnel.

This regulation explicitly includes individuals as subjects; claiming “I’m just an amateur” does not exempt anyone from compliance. Submitting vulnerabilities found in domestic systems to foreign bug bounty platforms violates the rule prohibiting disclosure to foreign entities. This rule addresses how vulnerabilities must be handled after discovery. Whether one is legally permitted to test systems depends on other provisions, such as the requirement for written authorization before testing any system. Even legally discovered vulnerabilities may incur penalties if disclosed improperly. Unauthorized testing results in violations on both fronts. Among reporting channels, the MIIT platform and CNCERT are most commonly used. The regulations do not specifically address cases where a vendor is notified but fails to act; in practice, documentation of negotiation and reporting processes is required before official submission.
