Publication date: 2026-07-11

Last updated on: 2026-07-13

Assigner: VulnCheck

Description

ImageMagick before 7.1.2-26 contains a use-after-free vulnerability in the FormatMagickCaption method when memory allocation fails. Attackers can trigger memory allocation failures to cause a dangling pointer to reference freed memory, potentially enabling denial of service or code execution.

Exploitability

CWE

KEV

CWE ID	Description
CWE-416	The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

Attack-Flow Graph

Executive Summary

CVE-2026-61861 is a use-after-free vulnerability in ImageMagick's FormatMagickCaption function that occurs when memory allocation fails.

This vulnerability happens because after a memory allocation error, a dangling pointer continues to reference memory that has already been freed.

This can lead to memory corruption or other unintended behaviors.

It affects ImageMagick versions prior to 7.1.2-26 and 6.9.13-51, with patches available in those versions.

Detection Guidance

There is no specific information provided about detection methods or commands to identify this vulnerability on a network or system.

Impact Analysis

This vulnerability can potentially enable denial of service or code execution by exploiting the dangling pointer referencing freed memory.

However, the severity is rated as Low with a CVSS score of 3.7 because it requires high attack complexity and does not impact confidentiality or integrity.

The main impact is limited to availability, meaning it could cause the application to crash or behave unexpectedly.

Compliance Impact

The provided information does not specify any direct impact of this vulnerability on compliance with common standards and regulations such as GDPR or HIPAA.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade ImageMagick to version 7.1.2-26 or later, or 6.9.13-51 or later, where the issue has been patched.
