ImageMagick is free and open-source software used for editing and manipulating digital images. This vulnerability allows the BilateralBlurImage method to allocate a set of double buffers inside AcquireBilateralTLS. However, in versions prior to 7.1.2-13, the last element in the set is not properly initialized. This will result in a release of an invalid pointer inside DestroyBilateralTLS when the memory allocation fails. Version 7.1.2-13 contains a patch for the issue.
The CVSS score for this vulnerability is 6.5, categorized as medium severity. The attack vector is network-based, requiring no privileges or user interaction. The potential impacts include low integrity and high availability risks.
Organizations utilizing ImageMagick should prioritize patching to mitigate risks associated with this vulnerability. Monitoring for updates and applying them promptly is essential to maintain security posture.
The vulnerability was published on January 20, 2026, and has been analyzed. Given the availability of a patch, organizations should assess their current version and take appropriate remediation actions.
Risk to organizations includes potential service disruption and unauthorized access stemming from this vulnerability. Attackers may leverage this flaw in environments where ImageMagick is deployed.
Vulnerability Details
