CVE-2026-109264 ImageMagick CVE debrief
ImageMagick before 6.9.13-57 and 7.x before 7.1.2-32 contains uncontrolled recursion in the MVG decoder that can exhaust the program stack. An attacker who controls a file name processed by ImageMagick can trigger a stack overflow that crashes the process, causing a denial of service. This vulnerability affects ImageMagick installations and can be exploited by providing a malicious file name, leading to potential system instability. Defenders should prioritize verifying and updating ImageMagick installations to prevent potential attacks.

- Denial-of-service attacks can be launched against vulnerable ImageMagick installations.
- Successful exploitation can cause the ImageMagick process to crash, leading to potential system instability.
- Defenders should verify and update ImageMagick installations to prevent potential attacks.
- Remediation priority is high for systems and applications that rely on ImageMagick for image processing.
Technical summary
The vulnerability exists in the MVG decoder of ImageMagick, where uncontrolled recursion can lead to a stack overflow. An attacker can trigger this overflow by providing a malicious file name, causing the process to crash and resulting in a denial of service. The affected versions of ImageMagick are before 6.9.13-57 and 7.x before 7.1.2-32. Defenders should prioritize verifying and updating ImageMagick installations to prevent potential denial-of-service attacks. The CVE Program record and NIST NVD detail page offer source-provided CVE metadata and vulnerability assessments.
Defensive priority
Defenders should prioritize verifying and updating ImageMagick installations to prevent potential denial-of-service attacks.
Recommended defensive actions
- Verify ImageMagick installations and update to version 6.9.13-57 or later, or 7.1.2-32 or later.
- Implement input validation and sanitization to prevent malicious file names from being processed.
- Monitor ImageMagick logs for potential denial-of-service attacks.
- 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.
