CVE-2026-116141 · Severity: medium · CVSS 5.3 · Published 2026-10-25

ImageMagick is an image processing library used to convert and manipulate image files across web applications and servers. A vulnerability in its UHDR image decoder allows attackers to bypass resource limits by submitting specially crafted images with oversized dimensions, causing the application to consume excessive CPU and memory before the limits are enforced, potentially leading to denial of service.

## How to fix

- Fixed in 7.1.2-33

## Technical details

The UHDR decoder in ImageMagick performs image dimension extent checks after decoding rather than before, allowing attackers to craft UHDR images with oversized width and height values that trigger full decode processing before policy enforcement. This is a policy bypass vulnerability (CWE-400, CWE-770) exploitable remotely without authentication or user interaction, resulting in uncontrolled resource allocation and potential availability impact. A fix exists in version 7.1.2-33 and later.
