Prior to 2.14.1, Mechanize::HTTP::Agent#response_redirect treats redirects as same-origin when the host matches without consistently comparing scheme and port. A same-host HTTPS-to-HTTP redirect can send Authorization and Cookie headers over cleartext, while a same-host redirect to another port can send a caller-supplied Cookie header to a different service. Cookies in Mechanize#cookie_jar remain scoped separately; the issue affects caller-supplied headers and can disclose credentials without affecting integrity or availability. This issue is fixed in version 2.14.1.","state":0,"publishedAt":"2026-10-08T21:26:16.092+00:00","modifiedAt":"2026-10-09T15:06:49.265+00:00","affected":[{"ecosystem":"Vendor product","name":"mechanize","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"sparklemotion\",\n                    \"product\": \"mechanize\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.15.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N","score":5.9,"severity":"MEDIUM"}],"references":["https://github.com/sparklemotion/mechanize/security/advisories/GHSA-5jgv-wc2m-xv99","https://github.com/sparklemotion/mechanize/pull/676","https://github.com/sparklemotion/mechanize/commit/02a1235842d6eda8d4a5a3d8f13aba2cecf52e4f","https://github.com/sparklemotion/mechanize/commit/2f97fe358a91928e5e48221f2ec5cb50fa1a43ba","https://github.com/sparklemotion/mechanize/releases/tag/v2.14.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-107714","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-107714","identifiers":["CVE-2026-107714"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
