23
FAUCET Score

CVE-2026-25765 is a Server-Side Request Forgery (SSRF) vulnerability affecting the Faraday HTTP client library prior to version 2.14.1. It arises from the build_exclusive_url method's use of Ruby's URI#merge, which incorrectly processes protocol-relative URLs, allowing an attacker to redirect requests to arbitrary hosts if user-controlled input is passed to Faraday's request methods. This vulnerability has a CVSS score of 5.8 (Medium) with a network attack vector and low impact on confidentiality. While there is no evidence of active exploitation or public exploit code, it has garnered some community discussion, including a mention of AI-powered discovery.
