Uncontrolled Search Path in ImageMagick on Windows

Publication date: 2026-10-11

Last updated on: 2026-10-11

Assigner: VulnCheck

Description
ImageMagick on Windows through 7.1.2-33 and 6.9.13-58 contains an uncontrolled search path vulnerability in NTGhostscriptEXE() that launches gswin64c.exe by bare name when Ghostscript is unregistered. Attackers can plant a malicious gswin64c.exe in the working directory to execute code with ImageMagick privileges when PDF, PostScript, or EPS files are converted.

Executive Summary

CVE-2026-108693 is an uncontrolled search path vulnerability in ImageMagick on Windows. When processing PDF, PostScript, or EPS files, ImageMagick may launch gswin64c.exe by bare name without a full path. Attackers can place a malicious gswin64c.exe in the working directory, which ImageMagick will execute with its privileges if Ghostscript is unregistered.

Detection Guidance

Check for unexpected gswin64c.exe processes running in directories where ImageMagick processes PDF, PS, or EPS files. Monitor for files named gswin64c.exe in untrusted directories. Use process monitoring tools like Process Explorer to detect ImageMagick launching executables by bare name.

Impact Analysis

This vulnerability allows attackers to execute arbitrary code on your system with the same privileges as ImageMagick. If you process untrusted PDF, PostScript, or EPS files, an attacker could place a malicious executable in the same directory and trick ImageMagick into running it.

Compliance Impact

This vulnerability could lead to unauthorized code execution with ImageMagick privileges, potentially allowing attackers to access, modify, or exfiltrate sensitive data processed by ImageMagick. This may violate GDPR's data integrity and confidentiality requirements or HIPAA's safeguards for protected health information if exploited in healthcare environments.

Mitigation Strategies

Configure ImageMagick to use absolute paths for Ghostscript by setting MAGICK_GHOSTSCRIPT_PATH environment variable. Avoid running ImageMagick conversions from untrusted directories. Disable PDF/PS delegate processing if not required. Update to a patched version once available.
