CVE-2025-1211 Details
Description
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://[email protected]/, 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.
A Server-side Request Forgery (SSRF) vulnerability has been identified in the Hackney package, versions prior to 1.21.0. This vulnerability arises from improper URL parsing by the built-in URI module and Hackney itself. When the URL 'http://[email protected]/' is processed, the URI module correctly identifies the host as '127.0.0.1', but Hackney mistakenly refers to the host as '127.2.2.2/'. This misinterpretation can be exploited in scenarios where users depend on the URI parsing for host validation.
Upgrade Hackney to version 1.21.0 or higher.
