How to Check if You Are Affected

To determine whether your application is affected by CVE-2026-25797, inspect your project dependencies for ImageMagick:

inspect dependencies for Magick.NET-Q16-AnyCPU

Analyze the terminal output to locate any version of ImageMagick in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 14.10.3), your application is affected.

Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-94: Improper Control of Generation of Code ('Code Injection'), where the product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. In ImageMagick, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

The ps encoders, responsible for writing PostScript files, fails to sanitize the input before writing it into the PostScript header. An attacker can provide a malicious file and inject arbitrary PostScript code. When the resulting file is processed by a printer or a viewer (like Ghostscript), the injected code is interpreted and executed. The html encoder does not properly escape strings that are written to in the html document. An attacker can provide a malicious file and injection arbitrary html code.
