Description

This security bulletin contains information about 1 vulnerability.


1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2026-33637)

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to redirect requests to an attacker-controlled host.

The vulnerability exists due to server-side request forgery in Faraday::Connection#build_exclusive_url when processing a protocol-relative URI object as a per-request target. A remote attacker can supply a crafted protocol-relative URI object to redirect requests to an attacker-controlled host.

Connection-scoped headers such as Authorization may be preserved on the off-host request.
