{"id":"CVE-2026-105326","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-105326","generatedAt":"2026-10-28T01:02:32.702Z","title":"An argument injection flaw was found in CUPS.","description":"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.","published":"2026-10-05T19:17:16.000Z","lastModified":"2026-10-07T18:17:16.000Z","status":"Awaiting Analysis","sourceIdentifier":"secalert@redhat.com","cvss":{"version":"3.1","score":2.5,"severity":"LOW","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:N/A:N"},"cwe":["CWE-88"],"affected":[],"epss":{"score":0.00217,"percentile":0.12025,"date":"2026-10-26","history":[{"date":"2026-10-06","score":0.00216,"percentile":0.10956}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.22%).
