{"id":"DEBIAN-CVE-2026-8368","details":"LWP::UserAgent versions before 6.83 for Perl leak Authorization and Proxy-Authorization headers on cross-origin redirects.  On a 3xx response, the redirect handler strips only Host and Cookie before issuing the follow-up request. Caller-supplied Authorization and Proxy-Authorization headers are sent unchanged to the redirect target, including across scheme, host, or port changes.  A redirect to an attacker controlled host therefore discloses the caller's credentials to that host.","modified":"2026-09-14T17:03:50.268262649Z","published":"2026-05-12T15:16:19.690Z","upstream":["CVE-2026-8368"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-8368"}],"affected":[{"package":{"name":"libwww-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libwww-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.68-1","6.70-1","6.71-1","6.71-2","6.72-1","6.73-1","6.76-1","6.77-1","6.78-1","6.80-1","6.81-1","6.82-1","6.83-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-8368.json"}},{"package":{"name":"libwww-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libwww-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.78-1","6.80-1","6.81-1","6.82-1","6.83-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-8368.json"}},{"package":{"name":"libwww-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libwww-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.83-1"}]}],"versions":["6.78-1","6.80-1","6.81-1","6.82-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-8368.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}
