CVE-2026-101258

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.
