CVE-2026-109276: ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 Temporary File Leak in JNG Decoder

Q: Which deployments are exposed to this issue?

Deployments using ImageMagick versions earlier than 6.9.13-57 or 7.1.2-32 are affected if they process JNG input. Systems that do not accept or process JNG files are not described as exposed by the available information.

Q: What does an attacker need to do to exploit it?

An attacker needs the ability to submit crafted JNG files for ImageMagick to process. No authentication, user interaction, or special attack complexity is indicated by the supplied vector.

Q: What is the practical impact?

Repeated processing of crafted JNG files can leave temporary files behind, consuming disk space and degrading availability. The provided data indicates an availability impact only, with no stated confidentiality or integrity impact.

Q: What versions should be used to remediate the issue?

Upgrade ImageMagick 6 to 6.9.13-57 or later, or ImageMagick 7 to 7.1.2-32 or later.

Updated

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an incomplete cleanup flaw in the JNG decoder that fails to remove temporary files when processing crafted input. Attackers can submit crafted JNG files for processing to repeatedly leak temporary files, consuming disk space and degrading availability.
