Associated Vulnerability

Title: Samba: samba: remote code execution in printing subsystem via unescaped job description (CVE-2026-4480)
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" substitution 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.
