inspect dependencies for Magick.NET-Q16-AnyCPU

How to Check if You Are Affected

To determine whether your application is affected by GHSA-hc76-7mpc-qjqh, 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-116: Improper Encoding or Escaping of Output, where the product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. as a result, the intended structure of the message is not preserved. 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

An incomplete fix of CVE-2026-25797 can result in code injection in the HTML encoder.
