{"id":"DEBIAN-CVE-2026-107399","details":"The Mechanize library is used for automating interaction with websites. Prior to 2.14.1, Mechanize applies no origin trust boundary in Mechanize::HTTP::Agent#response_follow_meta_refresh when Mechanize#follow_meta_refresh is enabled. A page containing a meta refresh to another origin causes headers configured through Mechanize#request_headers= to be reapplied to the refresh request, allowing an attacker who controls content in the crawl to capture bearer tokens or session cookies. The default configuration is not affected because follow_meta_refresh is false, and the exposure is limited to caller-supplied default headers. This issue is fixed in version 2.14.1.","modified":"2026-10-10T09:47:35.476684116Z","published":"2026-10-08T22:17:26.683Z","upstream":["CVE-2026-107399"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-107399"}],"affected":[{"package":{"name":"ruby-mechanize","ecosystem":"Debian:12","purl":"pkg:deb/debian/ruby-mechanize?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10.1-1","2.10.1-1.1","2.14.0-1","2.14.0-2","2.14.1-1","2.8.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-107399.json"}},{"package":{"name":"ruby-mechanize","ecosystem":"Debian:13","purl":"pkg:deb/debian/ruby-mechanize?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10.1-1","2.10.1-1.1","2.14.0-1","2.14.0-2","2.14.1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-107399.json"}},{"package":{"name":"ruby-mechanize","ecosystem":"Debian:14","purl":"pkg:deb/debian/ruby-mechanize?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.14.1-1"}]}],"versions":["2.10.1-1","2.10.1-1.1","2.14.0-1","2.14.0-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-107399.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:N/A:N"}]}
