CVE-2025-1211

Versions of the package hackney before 1.21.0 are vulnerable to Server-side Request Forgery (SSRF) due to improper parsing of URLs by URI built-in module and hackey. Given the URL http://127.0.0.1?@127.2.2.2/, the URI function will parse and see the host as 127.0.0.1 (which is correct), and hackney will refer the host as 127.2.2.2/. This vulnerability can be exploited when users rely on the URL function for host checking.

Summary		(es) Las versiones del paquete hackney a partir de la versión 0.0.0 son vulnerables a Server-side Request Forgery (SSRF) debido al análisis incorrecto de las URL por parte del módulo integrado URI y hackey. Dada la URL http://127.0.0.1?@127.2.2.2/, la función URI analizará y verá el host como 127.0.0.1 (lo cual es correcto), y hackney se referirá al host como 127.2.2.2/. Esta vulnerabilidad puede explotarse cuando los usuarios dependen de la función URL para la verificación del host.
