CVE-2026-19547: Artifex Ghostscript local privilege escalation via PostScript resource hijacking

CVE-2026-19547 · Severity: info · Published 2026-09-29

Ghostscript for Windows, a document processing application, is vulnerable to local privilege escalation through PostScript resource file hijacking. An authenticated local attacker can create a directory structure on C:\ and plant a malicious PostScript file that Ghostscript automatically loads and executes with its full process privileges, allowing arbitrary code execution with Ghostscript's privileges.

Vendors: Artifex Software.

Technical details

The vulnerability stems from Ghostscript searching for PostScript resource files (IdiomSet, ProcSet, Decoding) in predictable paths under C:\gs\ that do not exist by default, combined with Windows default ACLs allowing any authenticated user to create directories at the C:\ root. An attacker can create C:\gs\fonts\IdiomSet\ and plant a malicious PostScript file named Pscript5Idiom, which runs automatically during Ghostscript initialization before document processing, executing with the privileges of the Ghostscript process. The vulnerability requires local access with authentication and was fixed in version 10.08.0.
