What is CVE-2026-26283?

A vulnerability in the JPEG encoder of ImageMagick allows for Denial of Service by triggering an infinite loop when the encoder fails to write persistently. This is caused by a flawed 'continue' statement in the binary search loop. An attacker can exploit this flaw using crafted image files, leading to 100% CPU consumption and causing the process to hang. It is crucial for users to upgrade to ImageMagick versions 7.1.2-15 or 6.9.13-40 or later to protect against this issue.
