CVE-2026-24484 in ImageMagick
Summary
by MITRE • 02/24/2026
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, Magick fails to check for multi-layer nested mvg conversions to svg, leading to DoS. Versions 7.1.2-15 and 6.9.13-40 contain a patch.

ImageMagick represents a widely deployed image processing library that handles numerous graphic formats including mvg and svg files through its magick command-line utility. The vulnerability described in CVE-2026-24484 specifically targets the conversion process between multi-layered mvg (Magick Vector Graphics) and svg (Scalable Vector Graphics) formats. This flaw exists in the software's handling of nested conversion operations where multiple layers of mvg content are processed and converted to svg format. The vulnerability stems from insufficient validation within the image processing pipeline that fails to properly monitor or limit recursive conversion operations.
The technical implementation of this vulnerability allows an attacker to craft malicious mvg files containing nested layers that, when processed by vulnerable versions of ImageMagick, trigger excessive resource consumption during the conversion process. This leads to a denial of service condition where system resources such as memory and processing power become exhausted, rendering the affected system unable to process legitimate image conversion requests. The flaw operates at the core level of the image processing engine, specifically within the vector graphics handling routines that manage multi-layered file formats.
From an operational impact perspective, this vulnerability poses significant risk to systems that process user-uploaded images or handle batch image conversions. Web applications, content management systems, and automated image processing services that utilize ImageMagick are particularly vulnerable. The DoS condition can be triggered through simple file uploads or by submitting crafted mvg files to image processing endpoints, making it a low-effort but high-impact attack vector. Organizations relying on ImageMagick for digital asset management, print services, or web-based image processing workflows face potential service disruption and availability issues.
The patch implemented in versions 7.1.2-15 and 6.9.13-40 addresses this vulnerability by introducing proper validation mechanisms that monitor and limit nested conversion operations. This fix aligns with security best practices outlined in CWE-400, which addresses unrestricted resource consumption, and follows the ATT&CK technique T1499.004 for network denial of service. Organizations should immediately upgrade to the patched versions to eliminate this vulnerability. Additional mitigations include implementing file type restrictions, limiting conversion operations, and deploying input validation measures. The vulnerability demonstrates the importance of proper resource management in image processing libraries and highlights the need for comprehensive testing of file format conversion workflows. System administrators should also consider implementing monitoring solutions to detect unusual resource consumption patterns that might indicate exploitation attempts.
