CVE-2026-4480

9.0
CRITICAL · CVSS 3.1 · EPSS 13.9% (pctl 96)

Patch early

EPSS 13.9% — above the 10% action threshold.

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.
