What is CVE-2026-116151?

The JNG encoder in ImageMagick versions prior to 6.9.13-58 and 7.x before 7.1.2-33 is susceptible to a memory leak caused by improper memory management when processing specially crafted JNG images. An attacker can exploit this vulnerability by supplying a maliciously crafted image, leading to the leakage of memory resources. This condition can increase memory consumption, potentially leading to resource exhaustion and resulting in a limited denial of service for users and applications relying on ImageMagick for image processing.

Affected Version(s)

ImageMagick 7.0.0-0 < 7.1.2-33

ImageMagick 0 < 6.9.13-58

ImageMagick 7.1.2-33
