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."}],"source":{"advisory":"GHSA-5jgv-wc2m-xv99","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-09T15:06:36.604518Z","id":"CVE-2026-107714","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-09T15:06:49.265Z"}}]}}
