CVE-2026-53465
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 is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-25, a crafted multi-frame can result in a heap buffer over-write when encoding it with the SF3 encoder. This issue has been patched in version 7.1.2-25.
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 · high confidenceImageMagick versions prior to 7.1.2-25 contain a heap buffer overflow vulnerability in the SF3 encoder when processing a specially crafted multi-frame image. The vulnerability occurs during encoding operations where insufficient bounds checking allows data to be written beyond allocated heap memory boundaries, potentially leading to memory corruption or arbitrary code execution.

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.
-
Check if ImageMagick is installedRun `convert --version` or `magick --version` on Linux, or check installed programs on WindowsAffected if ImageMagick is present on the system
-
Determine the installed version numberParse the version output - look for the version string (for example: 7.1.2-20)Affected if Version number is less than 7.1.2-25
-
Confirm SF3 encoder is availableRun `magick -list format` or `identify -list format` and look for SF3 in the list of supported formatsAffected if SF3 encoder is listed as an available format
-
Identify image processing workflows using SF3Search logs, scripts, or applications that use ImageMagick to process image files with the SF3 format or multi-frame imagesAffected if The system processes multi-frame image files using the SF3 encoder
The system is affected if ImageMagick is installed with a version below 7.1.2-25 and the SF3 encoder is used to process untrusted multi-frame image files.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped7.1.2-25
Upgrade ImageMagick to version 7.1.2-25 or later. As a defense-in-depth measure, validate and sanitize image files from untrusted sources before processing, and disable the SF3 encoder if not required.
ImageMagick 7.1.2-25
- Check current ImageMagick version using 'convert --version' or 'magick --version'
- Upgrade ImageMagick to version 7.1.2-25 or later using your system's package manager (e.g., apt-get update && apt-get install imagemagick, yum update imagemagick, or brew upgrade imagemagick)
- Alternatively, compile ImageMagick from source by downloading version 7.1.2-25 or newer from imagemagick.org
- Verify the upgrade was successful by running 'magick --version' and confirming the version is 7.1.2-25 or higher
