What is CVE-2026-109281?

ImageMagick versions prior to 7.1.2-32 are prone to a heap buffer over-read vulnerability due to improper handling of the -fx option. This flaw allows attackers to exploit specific -fx operations, leading to the potential disclosure of sensitive out-of-bounds heap memory contents. This may expose limited information that could be leveraged in further attacks. It's crucial for users to upgrade to the patched versions to mitigate this risk and secure their systems.

Affected Version(s)

ImageMagick 7.1.0-21 < 7.1.2-32
