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.","published":"2026-10-08T22:17:27.000Z","lastModified":"2026-10-09T16:38:58.000Z","status":"Awaiting Analysis","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},"cwe":["CWE-200","CWE-319","CWE-522"],"affected":[],"epss":{"score":0.00229,"percentile":0.13532,"date":"2026-10-26","history":[{"date":"2026-10-09","score":0.00228,"percentile":0.12537}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.23%).
