CVE-2026-56368
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImageMagick before 7.1.2-15 contains a memory leak vulnerability in multiple coders that write raw pixel data where allocated objects are not properly freed. Attackers can trigger this leak by processing specially crafted images, causing memory exhaustion and denial of service.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceImageMagick before 7.1.2-15 contains a memory leak in multiple coders that handle raw pixel data. When processing specially crafted images, allocated memory objects are not properly freed, leading to unbounded memory growth and eventual denial of service through memory exhaustion.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify ImageMagick versionRun `convert --version` or `magick --version` from command line. If using ImageMagick 6, also try `identify -version`. Record the exact version number shown (e.g., 7.1.2-10 or 6.9.12-35).Affected if The version displayed is earlier than 6.9.13-40 for the 6.x branch, OR falls between 7.0.0-0 and 7.1.2-14 for the 7.x branch.
-
Confirm package manager versionOn Debian/Ubuntu run `dpkg -l | grep -i imagemagick`. On RHEL/CentOS run `rpm -qa | grep -i imagemagick`. On macOS with Homebrew run `brew list imagemagick`. Verify the version number matches what was found in step 1.Affected if The installed package version matches the vulnerable ranges from step 1.
-
Check for active ImageMagick processesRun `ps aux | grep -i magick` or `pgrep -a -i magick` to see if ImageMagick is currently processing images or running as a service (e.g., a web application using ImageMagick).Affected if ImageMagick is actively processing images and the version is in the affected range - memory leak can occur during such processing.
-
Verify raw pixel coders are availableRun `convert -list configure | grep DELEGATES` or check coders with `convert -list coder`. Look for raw pixel format support (like grayscale, rgb, or unspecified raw formats).Affected if Raw pixel format coders are present and the version is vulnerable - these are the coders where the memory leak occurs.
You are affected if ImageMagick version is below 6.9.13-40 (6.x branch) or between 7.0.0-0 and 7.1.2-14 (7.x branch), and the application processes images using raw pixel data coders.

dbcve · scoped6.9.13-407.1.2-15
Upgrade to ImageMagick 7.1.2-15 or later to obtain the patched version. Additionally, implement resource limits (e.g., memory caps, processing timeouts) on image processing services as a defense-in-depth measure.
7.1.2-15 (for 7.x branch) or 6.9.13-40 (for 6.x branch)
- 1. Check current ImageMagick version using 'convert -version' or 'magick -version'
- 2. For ImageMagick 7.x users: upgrade to version 7.1.2-15 or later
- 3. For ImageMagick 6.x users: upgrade to version 6.9.13-40 or later
- 4. Verify the upgrade was successful by running 'convert -version' and confirming the version number
- 5. Test image processing workflows to ensure normal operation
