CVE-2026-105823 ImageMagick CVE debrief

Who should care

Defenders responsible for ImageMagick installations, security teams, and developers using ImageMagick in their applications should assess exposure and prioritize verification and updates.

Why it matters

Defenders should care about CVE-2026-105823 because it describes a policy bypass vulnerability in the CUT encoder of ImageMagick, which could lead to application crashes or sensitive data leaks. Relevant roles include defenders, security teams, and developers using ImageMagick. Supported consequences include potential crashes and data leaks. Evidence limits include lack of information on exploitation, impact, and remediation beyond vendor advisories.

• Potential application crashes due to crafted input
• Possible leak of sensitive data through the CUT encoder
• Verification of ImageMagick versions and configurations is necessary
• Remediation priority for ImageMagick installations is medium to high

Technical summary

ImageMagick before 6.9.13-56 and 7.x before 7.1.2-31 lacks a security policy check in the CUT encoder, allowing configured security policies to be bypassed. Attackers can supply crafted input processed by the CUT encoder to crash the application or leak sensitive data. The vulnerability affects ImageMagick installations prior to version 7.1.2-31. Defenders should prioritize verifying and updating ImageMagick installations to version 7.1.2-31 or later, and assess exposure in their environments. The CVE record and source item provide details on the policy bypass vulnerability in the CUT encoder of ImageMagick.

Defensive priority

Defenders should prioritize verifying and updating ImageMagick installations to version 7.1.2-31 or later, and assess exposure in their environments.

Recommended defensive actions

• Verify ImageMagick installations and update to version 7.1.2-31 or later
• Assess exposure in environments using ImageMagick
• Monitor for potential crashes or sensitive data leaks
• 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

Evidence notes

The CVE record and source item provide details on the policy bypass vulnerability in the CUT encoder of ImageMagick. However, the corpus does not establish versions, exploitation, impact, or remediation beyond vendor advisories.
