CVE-2026-109271 ImageMagick CVE debrief

ImageMagick 7.1.2-30 before 7.1.2-32 contains a use after free vulnerability in the WBINFO decoder. When a memory allocation fails during image decoding, attackers can supply a crafted image that causes freed memory to be reused, crashing the application. This vulnerability affects ImageMagick installations, particularly those using version 7.1.2-30, and requires immediate attention to prevent potential application crashes and memory allocation failure conditions during image decoding.

This includes operators, platform administrators, vulnerability management teams, and security teams who need to review and monitor image decoding processes for potential memory allocation failures and implement compensating controls to prevent exploitation.

Why it matters

Defenders should care about CVE-2026-109271 because it affects ImageMagick 7.1.2-30 before 7.1.2-32, potentially causing application crashes due to a use after free vulnerability in the WBINFO decoder. Defenders responsible for ImageMagick installations should assess exposure, prioritize updating to version 7.1.2-32 or later, and implement compensating controls to prevent exploitation.

  • Potential application crashes due to use after free vulnerability
  • Need for verification of ImageMagick installations and updates
  • Possible memory allocation failure conditions during image decoding
  • Requirement for compensating controls to prevent exploitation

Technical summary

The vulnerability occurs in the WBINFO decoder of ImageMagick 7.1.2-30 before 7.1.2-32. When a memory allocation fails during image decoding, a use after free vulnerability is triggered, causing freed memory to be reused and crashing the application. This vulnerability affects ImageMagick installations, particularly those using version 7.1.2-30, and requires immediate attention to prevent potential application crashes and memory allocation failure conditions during image decoding. Defenders should prioritize verifying ImageMagick installations and updating to version 7.1.2-32 or later.

Defensive priority

Defenders should prioritize verifying ImageMagick installations and updating to version 7.1.2-32 or later.

Recommended defensive actions

  • Verify ImageMagick installations and update to version 7.1.2-32 or later
  • Review and monitor image decoding processes for potential memory allocation failures
  • Implement compensating controls to prevent exploitation
  • Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
  • Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
  • Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
  • Track exceptions, retest remediated assets, and close the item only after evidence is documented
