CVE-2026-101258

7.8 · HIGH

A flaw was found in Ghostscript.

Published Oct 6, 2026CWE-787EPSS 0.18%

Overview

CVE-2026-101258 is a high-severity vulnerability. It was published on October 6, 2026 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.

Technical description

A flaw was found in Ghostscript. When Ghostscript renders a crafted PostScript or EPS document, it can bypass the -dSAFER sandbox and execute arbitrary shell commands in the context of the Ghostscript process. The issue chains memory corruption in document parsing with disabling of internal path access controls at runtime. An attacker can deliver the document directly or through formats that delegate rendering to Ghostscript (for example EPS import or print conversion workflows). Successful exploitation can compromise confidentiality, integrity, and availability of data accessible to the process running Ghostscript.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
