CVE-2026-107210: ImageMagick resource exhaustion in MAT decoder

CVE-2026-107210 · Severity: medium · CVSS 5.3 · Published 2026-10-07

ImageMagick is a widely-used image editing tool employed by web servers, content management systems, and graphic design applications to process and transform images. A crafted MAT image file can exploit a flaw in the decoder that bypasses disk space restrictions, allowing an attacker to fill up a server's storage and cause a denial of service. Legitimate users and services relying on the affected system would experience outages or slowdowns.

Technologies: ImageMagick. Vendors: ImageMagick.

How to fix

Fixed in: 7.1.2-30, 6.9.13-55

Technical details

The MAT decoder in ImageMagick prior to 7.1.2-30 and 6.9.13-55 fails to enforce the configured resource policy limit when creating temporary files during decompression of highly compressed MAT images. An attacker can supply a crafted MAT file that decompresses to a size exceeding the security-policy limit, causing excessive disk space consumption and potentially exhausting storage. The vulnerability is fixed in versions 7.1.2-30 and 6.9.13-55.
