Samba: samba: remote code execution in printing subsystem via unescaped job description_CVE-2026-4480

{
    "lastseen": "",
    "description": "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.",
