Claude Code approval option can save secrets to settings files that leak to public GitHub repositories

Apiiro◼ researchers found that Claude Code◆'s "Yes, and don't ask again" option stores approved shell commands, including embedded passwords and API keys, in .claude/settings.local.json. Across 104,185 public copies of that file, they identified 2,539 distinct secrets in 1,994 repositories, affecting 63 organisations, including 379 database passwords, 122 Supabase service-role keys and 43 SSH logins. Standard scanners Gitleaks◆ and TruffleHog missed 215 of the 1,122 affected local settings files.
