{"id":"DEBIAN-CVE-2026-105326","details":"An argument injection flaw was found in CUPS. When email notification is configured, the CUPS scheduler accepts printer subscription requests that supply a mailto notify-recipient-uri. The mailto notifier passes the recipient address to the configured sendmail program without ensuring it cannot be interpreted as command-line options. A remote attacker who can reach the CUPS service could supply a crafted recipient value starting with \"-\" to influence sendmail behavior. Successful exploitation depends on the installed mail transfer agent and CUPS network exposure, and may lead to execution of attacker-controlled commands with the privileges of the CUPS service user.","modified":"2026-10-06T05:00:06.222815419Z","published":"2026-10-05T19:17:16.393Z","upstream":["CVE-2026-105326"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-105326"}],"affected":[{"package":{"name":"cups","ecosystem":"Debian:12","purl":"pkg:deb/debian/cups?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.10-1","2.4.10-2","2.4.10-3","2.4.10-4","2.4.14-1","2.4.15-1","2.4.16-1","2.4.17-1","2.4.18-1","2.4.2-3","2.4.2-3+deb12u1","2.4.2-3+deb12u2","2.4.2-3+deb12u3","2.4.2-3+deb12u4","2.4.2-3+deb12u5","2.4.2-3+deb12u6","2.4.2-3+deb12u7","2.4.2-3+deb12u8","2.4.2-3+deb12u9","2.4.2-4","2.4.2-5","2.4.2-6","2.4.7-1","2.4.7-1.1","2.4.7-1.2","2.4.7-2","2.4.7-3"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-105326.json"}},{"package":{"name":"cups","ecosystem":"Debian:13","purl":"pkg:deb/debian/cups?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.10-3","2.4.10-3+deb13u1","2.4.10-3+deb13u2","2.4.10-4","2.4.14-1","2.4.15-1","2.4.16-1","2.4.17-1","2.4.18-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-105326.json"}},{"package":{"name":"cups","ecosystem":"Debian:14","purl":"pkg:deb/debian/cups?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.10-3","2.4.10-4","2.4.14-1","2.4.15-1","2.4.16-1","2.4.17-1","2.4.18-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-105326.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
