CVE-2026-22770: ImageMagick vulnerable to Release of Invalid Pointer in BilateralBlur when memory allocation fails

• Severity: critical (CVSS 9.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.4% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-01-20 · updated 2026-06-17
• Weakness: CWE-763

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.

Affected products

• ImageMagick: before 7.1.2-13 — fixed in 7.1.2-13

How to fix

Upgrade to a fixed version: ImageMagick 7.1.2-13. Check the vendor advisory for mitigations.
