THE Samba Team has released urgent security patches to address multiple critical vulnerabilities that threaten enterprise file servers globally. Two severe remote code execution flaws, CVE-2026-4480 and CVE-2026-4408, have been identified with perfect CVSS scores of 10.0. The former allows unauthorized users to execute scripts through the printing subsystem, while the latter exposes the password verification mechanism to exploitation by remote attackers.
Additionally, two high-severity access control flaws (CVE-2026-1933 and CVE-2026-3012) risk unauthorized access and denial of service via corrupted packets (CVE-2026-3238). Administrators are urged to immediately apply the updates or implement manual workarounds to secure systems.
