BEIJING, July 8 (Reuters) – A cybersecurity platform operated by China’s industry ministry warned on Wednesday that it had ​identified a serious security “backdoor” risk ‌in Anthropic’s AI coding tool, Claude Code.

• In a statement posted on its WeChat account, the National Vulnerability Database (NVDB) said Claude Code contains ‌a ​built-in monitoring mechanism capable ⁠of transmitting sensitive ⁠information, including users’ geographic location and identity-related identifiers, to remote servers without users’ consent.

• The warning applies to Claude ​Code versions 2.1.91 through 2.1.196.

• NVDB advised that organizations and users should ⁠immediately review affected systems ⁠and either uninstall the impacted ​versions or upgrade to the latest secure ​release in which the alleged backdoor ‌code has been removed.

• It also urged organizations to tighten controls on external network access for development tools and ⁠strengthen traffic monitoring on core business networks to prevent the unauthorized transfer of sensitive data.

• China’s ⁠Alibaba ‌has banned employees from using ⁠Claude Code at work after ​the ‌tool drew scrutiny for features ​that can ⁠help identify China-linked users, Reuters reported last week.

• Anthropic did not immediately reply to a Reuters request for comment.
