  • •CVE-2026-101258 allows arbitrary command execution via Ghostscript.
  • •Exploitation requires user interaction to process crafted documents.
  • •Public proof-of-concept code raises concerns about potential exploitation.

A vulnerability (CVE-2026-101258) in Ghostscript allows crafted PostScript and EPS documents to bypass the -dSAFER sandbox, enabling arbitrary command execution within the Ghostscript process. This flaw results from memory corruption during document parsing and the disabling of internal path access controls. Attackers can exploit this by delivering malicious documents through various workflows, requiring user interaction for processing. The vulnerability is rated as Important severity due to the potential for compromising confidentiality, integrity, and availability of data. Currently, exploitation status is unconfirmed, but a public proof-of-concept (PoC) exists, raising concerns about its reproducibility. Affected systems include print servers and document conversion services that utilize Ghostscript. Users are advised to monitor for unusual submissions and apply patches once available.
