CVE-2026-14780

Estado: Pendiente de análisisAlta (7.5)—

A vulnerability exists in the PaperCut NG/MF platform's device-scripting functionality due to insufficient sanitization and access restrictions within the embedded execution engine. An authenticated user with administrative access to the management interface can supply a malicious script that escapes the runtime sandbox.

A successful execution enables an attacker to run unauthorized operating system commands with administrative privileges on the host operating system.

CVSS
