Hi,

The following vulnerability was published for ruby-faraday.

CVE-2026-33637[0]:
| 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.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
