Overview

curl-cffi is a python binding for curl-impersonate via cffi.

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the handling of user-supplied URLs and automatic redirect following in the get function. An attacker can access internal network resources and retrieve sensitive information by supplying a crafted URL that triggers a redirect to internal services, potentially bypassing network controls through TLS fingerprint impersonation.
