CVE-2026-106566 ImageMagick CVE debrief

ImageMagick versions before 7.1.2-32 are vulnerable to a policy bypass in delegate symlink cleanup due to a missing check of the MAGICK_SHRED_PASSES environment variable. This allows a local privileged workflow to overwrite a file with random data. The vulnerability exists because the delegate symlink cleanup process does not properly validate the MAGICK_SHRED_PASSES environment variable, leading to potential local privilege escalation and data corruption. System administrators and developers using ImageMagick should assess exposure and prioritize updating to version 7.1.2-32 or later.

Who should care

System administrators and developers using ImageMagick, especially in environments where local privileged workflows exist, should assess exposure and prioritize updating to version 7.1.2-32 or later. This includes reviewing and adjusting the MAGICK_SHRED_PASSES environment variable, monitoring systems for potential exploitation, and implementing compensating controls for exposed systems.

Why it matters

This vulnerability allows a local privileged workflow to overwrite a file with random data, potentially leading to local privilege escalation and data corruption.

  • Local privilege escalation is possible
  • Data overwrite with random data

Technical summary

The vulnerability exists in the delegate symlink cleanup process of ImageMagick, where a missing check of the MAGICK_SHRED_PASSES environment variable allows a local privileged workflow to overwrite a file with random data. This issue can lead to local privilege escalation and data corruption. The vulnerability is fixed in ImageMagick version 7.1.2-32. Affected users should update to the latest version and review their environment for potential exposure. The MAGICK_SHRED_PASSES environment variable should be reviewed and adjusted as necessary to prevent exploitation.

Defensive priority

Medium priority for systems using ImageMagick, especially in environments where local privileged workflows exist.

Recommended defensive actions

  • Update ImageMagick to version 7.1.2-32 or later
  • Review and adjust the MAGICK_SHRED_PASSES environment variable
  • Monitor systems using ImageMagick for potential exploitation
  • Review compensating controls for exposed systems while remediation is scheduled and verified
  • Check relevant monitoring, detection, and logs for exposed assets that need extra review
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
