ImageMagick MIFF decoder infinite loop CPU exhaustion prior to 7.1.2.23/6.9.13-48
CVE-2026-46522 Published on June 10, 2026
ImageMagick: Infinite Loop in the MIFF decoder can lead to CPU exhaustion
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2.23 and 6.9.13-48, due to a missing check in the MIFF decoder, a crafted file could cause an infinite loop resulting in CPU exhaustion. Versions 7.1.2.23 and 6.9.13-48 fix the issue.
Vulnerability Analysis
CVE-2026-46522 is exploitable with network access, and does not require authorization privileges or user interaction. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have no impact on confidentiality and integrity, and a high impact on availability.
Weakness Types
What is a Resource Exhaustion Vulnerability?
The software does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources.
CVE-2026-46522 has been classified to as a Resource Exhaustion vulnerability or weakness.
What is an Infinite Loop Vulnerability?
The program contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. If the loop can be influenced by an attacker, this weakness could allow attackers to consume excessive resources such as CPU or memory.
CVE-2026-46522 has been classified to as an Infinite Loop vulnerability or weakness.
