CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:HSummary
CVE-2026-26283 is a medium-severity Infinite Loop (CWE-835) vulnerability in Imagemagick Imagemagick. Its CVSS base score is 6.2 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Application or System Exploitation (T1499.004); ranked at the 25th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-2 (Flaw Remediation) — see the control section below for these in your framework.

CVE-2026-26283 is a denial-of-service vulnerability in ImageMagick, a free and open-source software suite for editing and manipulating digital images. The issue stems from a `continue` statement in the JPEG extent binary search loop within the JPEG encoder, which triggers an infinite loop when image writing persistently fails. This affects ImageMagick versions prior to 7.1.2-15 (for the 7.x series) and 6.9.13-40 (for the 6.x series), earning a CVSS v3.1 base score of 6.2 (AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) and mapping to CWE-835 (Infinite Loop).
A local attacker with no privileges required can exploit this vulnerability by supplying a specially crafted image to an affected ImageMagick instance. The low attack complexity and lack of user interaction mean that processing the malicious image leads to 100% CPU consumption and a process hang, resulting in a denial of service on the targeted system or application.
The ImageMagick GitHub security advisory (GHSA-gwr3-x37h-h84v) confirms that versions 7.1.2-15 and 6.9.13-40 include patches to address the infinite loop. Security practitioners should update to these fixed versions and validate image inputs in applications using ImageMagick for processing, especially in local or automated workflows.
