China warns users of alleged ‘security backdoor vulnerabilities’ in Anthropic’s Claude Code, tells users to uninstall for security reasons

• China’s National Vulnerability Database warns that Claude Code contains spyware
• Alibaba recently banned Claude from internal use due to fears of user tracking
• Anthropic says it’s designed to prevent model distillation and illegal use

China has accused Anthropic’s Claude Code of containing what it describes as “security backdoor vulnerabilities” after the country’s National Vulnerability Database (CNVDB) found mechanisms capable of transferring user information to Anthropic servers without explicit user permission.

Researchers accuse the software vendor of collecting information such as user identity, geographic location, system environment information and other machine metadata.
