CVE-2026-4480: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Red Hat Red Hat Enterprise Linux 10
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.
