{"id":"DEBIAN-CVE-2023-46218","details":"This flaw allows a malicious HTTP server to set \"super cookies\" in curl that are then passed back to more origins than what is otherwise allowed or possible. This allows a site to set cookies that then would get sent to different and unrelated sites and domains.  It could do this by exploiting a mixed case flaw in curl's function that verifies a given cookie domain against the Public Suffix List (PSL). For example a cookie could be set with `domain=co.UK` when the URL used a lower case hostname `curl.co.uk`, even though `co.uk` is listed as a PSL domain.","modified":"2026-09-15T09:02:46.341845970Z","published":"2023-12-07T01:15:07.160Z","upstream":["CVE-2023-46218"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-46218"}],"affected":[{"package":{"name":"curl","ecosystem":"Debian:12","purl":"pkg:deb/debian/curl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.88.1-10+deb12u5"}]}],"versions":["7.88.1-10","7.88.1-10+deb12u1","7.88.1-10+deb12u1~bpo11+1","7.88.1-10+deb12u2","7.88.1-10+deb12u3","7.88.1-10+deb12u3~bpo11+1","7.88.1-10+deb12u4","7.88.1-10+deb12u5~bpo11+1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-46218.json"}},{"package":{"name":"curl","ecosystem":"Debian:13","purl":"pkg:deb/debian/curl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.5.0-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-46218.json"}},{"package":{"name":"curl","ecosystem":"Debian:14","purl":"pkg:deb/debian/curl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"8.5.0-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2023-46218.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
