China flags 'backdoor' vulnerabilities in Anthropic's Claude Code

By PulseAugur Editorial · [5 sources] ·

China's National Vulnerability Database has issued a warning regarding Anthropic's Claude Code, alleging that certain versions contain security backdoor vulnerabilities. The government claims a monitoring mechanism within the tool, active between April and June 2026, could send sensitive user information to remote servers without consent. While the tool is not officially approved for public use in China, and Anthropic has restricted its use in the region, the advisory suggests users uninstall or update the software. Anthropic has stated this was an experimental feature to prevent account abuse and model distillation, with plans to roll it back. AI
