CVE-2026-22770
CWE-763Published: January 20, 2026· Updated: Jun 17, 2026
Official Description
ImageMagick is free and open-source software used for editing and manipulating digital images. The BilateralBlurImage method will allocate a set of double buffers inside AcquireBilateralTLS. But, 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.
Risk Analysis
ImageMagick has an improper initialization flaw in the BilateralBlurImage method that can lead to an invalid pointer release when memory allocation fails. This could potentially be leveraged to cause a crash or other undefined behavior.
No public exploit is known, and it is not in the KEV. The vulnerability is remotely exploitable with low complexity.
Upgrade ImageMagick to version 7.1.2-13 to include the patch for this memory management issue.
Technical Analysis
CVE-2026-22770 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
