{"id":"ALPINE-CVE-2026-4480","details":"A flaw was found in the Samba printing subsystem. Samba passes the client-controlled job description string to the command configured with the \"print command\" setting via the \"%J\"\nsubstitution character without escaping shell meta characters. A remote attacker could exploit this vulnerability by sending a specially crafted print job description that contains unescaped shell characters. This could lead to remote code execution on the affected system.","modified":"2026-08-27T22:17:57.321360194Z","published":"2026-05-26T15:16:40.937Z","upstream":["CVE-2026-4480"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2026-4480"}],"affected":[{"package":{"name":"samba","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.1.0"},{"fixed":"4.22.10-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-4480.json"}},{"package":{"name":"samba","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/samba?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.1.0"},{"fixed":"4.23.8-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2026-4480.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
