Claude Code reportedly sent a user's email address to websites via HTTP headers

Severity

A GitHub issue reports that included a user's email address in HTTP User-Agent headers sent to third-party websites during web searches. The reporter used version 2.1.318 on macOS and said they now receive dozens of scam emails a day, but no raw request or reproduction steps were provided. Commenters said the built-in cc-plugin-privacy guard, which is enabled by default from version 2.1.317, did not reliably block the behaviour, and an employee acknowledged gaps in the interim protection.

What to do

  1. Review network commands written by coding agents before allowing them web access.
  2. Verify that privacy controls in Claude Code are active rather than assuming the built-in guard works.
  3. Check which Claude Code version is installed and whether the cc-plugin-privacy module is present and enabled.
