Report: CVE-2026-33637 - Faraday: Protocol-relative URI objects still bypass host scoping (possible incom
CVE ID :CVE-2026-33637 Published : May 19, 2026, 7:16 p.m. | 46 minutes ago Description :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. Severity: 0.0 | NONE Visit the link for more details, such as CVSS details, affected products, timeline, and more...
