Claude Code leaks email via User-Agent, spamming users
What is Claude Code sends your email address to websites?
Anthropic's Claude Code app adds the user's email address to the HTTP User-Agent header when it performs web searches. The exposed address is harvested by sites, leading to a flood of scam emails.
