{"id":"DEBIAN-CVE-2026-59883","details":"Guzzle is an extensible PHP HTTP client. Prior to 7.12.3, CookieJar did not restrict cookies scoped to IP-address or bare-numeric Domain values to the exact host that set them, because SetCookie::matchesDomain() applied ordinary suffix matching to domains such as 192.168.0.1, [::1], or 1, allowing cross-host cookie disclosure, cookie injection, or session fixation. This issue is fixed in version 7.12.3.","modified":"2026-08-27T23:06:14.077599124Z","published":"2026-07-08T17:17:26.737Z","upstream":["CVE-2026-59883"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-59883"}],"affected":[{"package":{"name":"guzzle","ecosystem":"Debian:12","purl":"pkg:deb/debian/guzzle?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.11.0-1","7.12.0-1","7.12.1-1","7.12.3-1","7.13.1-1","7.14.0-1","7.14.1-1","7.14.2-1","7.15.0-1","7.15.1-1","7.15.2-1","7.15.3-1","7.15.5-1","7.4.5-1","7.9.2-0.1","8.0.1-1","8.0.2-1","8.1.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59883.json"}},{"package":{"name":"guzzle","ecosystem":"Debian:13","purl":"pkg:deb/debian/guzzle?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["7.11.0-1","7.12.0-1","7.12.1-1","7.12.3-1","7.13.1-1","7.14.0-1","7.14.1-1","7.14.2-1","7.15.0-1","7.15.1-1","7.15.2-1","7.15.3-1","7.15.5-1","7.9.2-0.1","8.0.1-1","8.0.2-1","8.1.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59883.json"}},{"package":{"name":"guzzle","ecosystem":"Debian:14","purl":"pkg:deb/debian/guzzle?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.12.3-1"}]}],"versions":["7.11.0-1","7.12.0-1","7.12.1-1","7.9.2-0.1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59883.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
