Impact

Memory corruption that can be exploited for arbitrary code execution, information disclosure, or denial of service. With a CVSS score of 5.3 (MEDIUM), this represents a moderate risk.
Exploit ScenarioDerived

An attacker triggers a specific sequence of operations that causes the application to free a memory block and then reference it again, potentially executing attacker-controlled data.

AnalysisAIv1 – Mar 12, 2026

Heap use-after-free in ImageMagick's MSL decoder (versions before 7.1.2-16 and 6.9.13-41) allows remote attackers to trigger memory access violations via specially crafted MSL files, resulting in denial of service. The vulnerability requires no authentication or user interaction and affects systems processing untrusted image files. No patch is currently available for this MEDIUM severity issue.

DescriptionGitHub Advisory

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, a heap use-after-free vulnerability in ImageMagick's MSL decoder allows an attacker to trigger access to freed memory by crafting an MSL file. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41.

Executive ViewAI

Why It Matters

Organizations using ImageMagick should be aware of moderate risk from CVE-2026-28687, a use-after-free vulnerability rated CVSS 5.3. Exploitation could compromise the security of affected deployments. Organizations should apply vendor updates when available and monitor for exploitation.

Business Impact: Low
Compensating Controls

Apply vendor patch. If patching is delayed: enable ASLR/DEP, apply network segmentation.
