CVE-2026-109259 ImageMagick CVE debrief

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an uninitialized memory read in the TGA image decoder that can expose memory contents. Attackers can supply a crafted TGA image for processing to disclose contents of uninitialized memory from the ImageMagick process. This vulnerability has a medium severity with a CVSS score of 6.9. Defenders should assess exposure and prioritize updates to prevent potential memory disclosure. The vulnerability affects ImageMagick installations, particularly those using versions before 6.9.13-57 and 7.x before 7.1.2-32.

Who should care

Defenders responsible for ImageMagick installations, particularly those using versions before 6.9.13-57 and 7.x before 7.1.2-32, should assess exposure and prioritize updates to prevent potential memory disclosure.

Why it matters

CVE-2026-109259 is a medium-severity vulnerability in ImageMagick that can lead to information disclosure through a crafted TGA image. Defenders should prioritize verifying and updating ImageMagick installations to prevent potential memory disclosure. The vulnerability has a CVSS score of 6.9 and is considered medium severity.

  • Potential disclosure of sensitive memory contents
  • Increased risk of data exposure through crafted TGA images
  • Need for verification of ImageMagick version and updates
  • Potential impact on confidentiality due to memory disclosure

Technical summary

ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains an uninitialized memory read in the TGA image decoder. This vulnerability can be exploited by supplying a crafted TGA image for processing, potentially disclosing contents of uninitialized memory from the ImageMagick process. The vulnerability affects ImageMagick installations, particularly those using versions before 6.9.13-57 and 7.x before 7.1.2-32. Defenders should prioritize verifying and updating ImageMagick installations to prevent potential memory disclosure. The vulnerability has a CVSS score of 6.9 and is considered medium severity.

Defensive priority

Defenders should prioritize verifying and updating ImageMagick installations to prevent potential memory disclosure.

Recommended defensive actions

  • Verify ImageMagick version and update to 6.9.13-57 or 7.1.2-32 if necessary
  • Restrict input to ImageMagick TGA decoder to prevent crafted image processing
  • Monitor ImageMagick process logs for potential memory disclosure attempts
  • Implement additional monitoring for ImageMagick processes
  • Review compensating controls for exposed systems
  • Conduct an asset inventory to identify affected systems
  • Track exceptions and retest remediated assets
