CVE-2026-25765
Description
A flaw was found in Faraday, an HTTP client library. The build_exclusive_url method, which combines a base URL with a user-supplied path, incorrectly processes protocol-relative URLs (e.g., //evil.com/path). This allows a remote attacker to supply a specially crafted URL, leading to Server-Side Request Forgery (SSRF). An attacker can exploit this to redirect requests to an arbitrary host, potentially accessing internal resources or bypassing security controls.
Statement
MODERATE: The Faraday HTTP client library, used in Red Hat 3scale API Management Platform and OpenShift Container Platform components, is vulnerable to Server-Side Request Forgery (SSRF). This flaw allows an attacker to redirect requests to arbitrary hosts if user-controlled input is passed to Faraday's request methods, due to incorrect processing of protocol-relative URLs.
Mitigation
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
The following CVSS metrics and score provided are preliminary and subject to review.
