CRLF Injection Into PHP's cURL Options
CRLF Injection Into PHP’s cURL Options
PHP's cURL header options never reject carriage returns and line feeds, so user data reflected into a server-side API request header can inject extra headers. Adding a double CRLF plus a forged Content-Length lets an attacker append his own request body, making the internal API act on an attacker-chosen method instead of the legitimate one.
