      <title>CVE-2026-33637 — Faraday: Protocol-relative URI objects still bypass host scoping (possible incomplete fix for GHSA-33mh-2634-fwr2)</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-33637</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; lostisland faraday&lt;/p&gt;
&lt;p&gt;Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters. Versions 2.0.0 through 2.14.1 still allow protocol-relative host override when the request target is passed as a URI object (rather than a String) to Faraday::Connection#build_exclusive_url. This bypasses the February 2026 fix for GHSA-33mh-2634-fwr2 and enables off-host request forgery: a request built from a fixed-base Faraday::Connection can be redirected to an attacker-controlled host, forwarding connection-scoped values such as Authorization headers and default query parameters. This issue has been fixed in version 2.14.3.&lt;/p&gt;</description>
