curl_cffi: Redirect-based SSRF leads to internal network access in curl_cffi (with TLS impersonation bypass)

Summarycurlcffi does not restrict requests to internal IP ranges, and follows redirects automatically via the underlying libcurl.Because of this, an attacker-controlled URL can redirect requests to internal services such as cloud metadata endpoints. In addition, curlcffi’s TLS impersonation featu...
