Anthropic's Claude Code Leaks User Emails in User-Agent
Anthropic's AI coding agent Claude Code has been found to transmit users' account email addresses in the User-Agent header during web requests, potentially exposing them to third-party websites. A GitHub bug report titled 'Privacy violation in User-Agent header' triggered the disclosure, with one affected developer attributing dozens of daily scam emails to this leak. The issue gained traction on Hacker News, topping the charts with over 1,000 points and 300 comments. Anthropic acknowledged the flaw, apologized, and announced a fix: removing the email from the model context in the next release. A built-in extension, 'cc-plugin-privacy', is set to block this behavior by default from version 2.1.317, though the current stable channel is behind and a user reported the protection failed their test. The incident raises GDPR concerns for European companies and comes at a sensitive time as Anthropic prepares for an IPO, facing competition from OpenAI's Codex and other coding tools, though it also notes that the actual link to the spam wave is not confirmed.
