CVE-2026-109269 · Severity: medium · CVSS 5.3 · Published 2026-10-12

ImageMagick is an image processing library used by web applications, servers, and desktop software to convert and manipulate image files. A flaw in its JPEG decoder can leak uninitialized memory when processing a maliciously crafted JPEG file, potentially exposing sensitive data such as encryption keys or authentication tokens that happened to be in memory.

## How to fix

- Fixed in ImageMagick 6.9.13-57, 7.1.2-32

## Technical details

The JPEG decoder in ImageMagick performs an uninitialized memory read when handling certain crafted JPEG inputs, triggered by improper bounds checking. An attacker can supply a malicious JPEG file to an application using the library to trigger the disclosure; no authentication or user interaction beyond opening the file is required. The vulnerability allows information disclosure with low confidentiality impact.

## Affected products

- ImageMagick ImageMagick 6.9.13-56 and earlier; 7.x before 7.1.2-32
