CVE-2026-48734: ImageMagick stack overflow in MVG decoder

CVE-2026-48734 · Severity: medium · CVSS 5.5 · Published 2026-06-10

Vendors: ImageMagick.

Executive brief

ImageMagick is a widely used software suite for displaying, converting, and editing image files. A vulnerability in its MVG (Magick Vector Graphics) decoder allows a specially crafted image file to crash the application. This could lead to a denial-of-service, potentially disrupting automated image processing workflows or applications that rely on this library.

Technical details

A stack overflow vulnerability exists in ImageMagick's MVG (Magick Vector Graphics) decoder due to uncontrolled recursion (CWE-674). The root cause is a missing depth or visited-set check during the decoding process. An attacker can exploit this by providing a specially crafted MVG file, which triggers excessive recursion and consumes the program stack. This is a local attack requiring user interaction (opening the file) and results in a denial-of-service (application crash). The issue is addressed in Magick.NET version 14.14.0.
