ruby-mechanize: The Mechanize library is used for automating interaction with websites
CVE-2026-107714 is fixed in ruby-mechanize on 1 platform by DEBIAN-CVE-2026-107714 (version 2.14.1-1), released October 9, 2026. It is not reported as exploited. Patch Radar priority: Routine.
The Mechanize library is used for automating interaction with websites. 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.
