What is CVE-2026-116152?

ImageMagick versions prior to 7.1.2-33 are susceptible to a memory leak vulnerability in the MAT decoder. This flaw arises when an attacker crafts specific MAT files that exploit certain error conditions, leading to a series of memory leaks. As these files are processed repeatedly, the application can gradually consume an increasing amount of process memory, potentially impacting performance and stability.

Affected Version(s)

ImageMagick 0 < 7.1.2-33
