Prior to 2.14.1, Faraday's build_exclusive_url method (in lib/faraday/connection.rb) uses Ruby's URI#merge to combine the connection's base URL with a user-supplied path. Per RFC 3986, protocol-relative URLs (e.g. //evil.com/path) are treated as network-path references that override the base URL's host/authority component. This means that if any application passes user-controlled input to Faraday's get(), post(), build_url(), or other request methods, an attacker can supply a protocol-relative URL like //attacker.com/endpoint to redirect the request to an arbitrary host, enabling Server-Side Request Forgery (SSRF). This vulnerability is fixed in 2.14.1.","published_at":"2026-02-09T20:30:58.774000Z","last_modified_at":null,"cvss_v3_score":5.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-918"],"nvd_references":["https://github.com/lostisland/faraday/security/advisories/GHSA-33mh-2634-fwr2","https://github.com/lostisland/faraday/commit/a6d3a3a0bf59c2ab307d0abd91bc126aef5561bc","https://github.com/lostisland/faraday/releases/tag/v2.14.1"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:26.759302Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"C","value_label":"Changed"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"lostisland","vendor_name":"lostisland","product_slug":"faraday","product_name":"faraday","version_start":"< 2.14.1","version_start_inclusive":true,"version_end":"< 2.14.1","version_end_inclusive":true,"cpe23_uri":"cve5:lostisland:faraday:< 2.14.1:< 2.14.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/lostisland/faraday/security/advisories/GHSA-33mh-2634-fwr2","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/lostisland/faraday/commit/a6d3a3a0bf59c2ab307d0abd91bc126aef5561bc","source_type":"PATCH","tags":["patch"]},{"url":"https://github.com/lostisland/faraday/releases/tag/v2.14.1","source_type":"PATCH","tags":["patch"]}],"timeline":[{"type":"published","at":"2026-02-09T20:30:58.774000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:12.012794Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:12.012794Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:12.012794Z","label":"CVSS score revised","source":"cvelistv5"}]}
