Claude Code is an agentic coding tool. Prior to version 1.0.111, Claude Code contained insufficient URL validation in its trusted domain verification mechanism for WebFetch requests. The application used a startsWith() function to validate trusted domains (e.g., docs.python.org, modelcontextprotocol.io), this could have enabled attackers to register domains like modelcontextprotocol.io.example.com that would pass validation. This could enable automatic requests to attacker-controlled domains without user consent, potentially leading to data exfiltration. This issue has been patched in version 1.0.111.

- GHSA-vhw5-3g5m-8ggfClaude Code has a Domain Validation Bypass which Allows Automatic Requests to Attacker-Controlled Domains2026-02-03ghsa · osvUS
Claude Code contained insufficient URL validation in its trusted domain verification mechanism for WebFetch requests. The application used a `startsWith()` function to validate trusted domains (e.g., `docs.python.org`, `modelcontextprotocol.io`), this could have enabled attackers to register domains like `modelcontextprotocol.io.example.com` that would pass validation. This could enable automatic requests to attacker-controlled domains without user consent, potentially leading to data exfiltration. Users on standard Claude Code auto-update have received this fix already. Users performing manual updates are advised to update to the latest version.
