DeepSeek TUI has SSRF via HTTP Redirect Bypass in fetch_url Tool
### Summary The `fetch_url` tool validates the initial URL's resolved IP address against a restricted-IP blocklist (`is_restricted_ip()`) to prevent SSRF attacks against internal services (cloud metadata endpoints, localhost, private networks). However, the HTTP client (`reqwest`) is configured to automatically follow up to 5 redirects (`reqwest::r...
