CVE-2026-33908: ImageMagick is vulnerable to Stack Overflow in DestroyXMLTree()

• Severity: high (CVSS 7.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.5% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-04-13 · updated 2026-07-15
• Weakness: CWE-674

Description

ImageMagick is free and open-source software used for editing and manipulating digital images. In versions below both 7.1.2-19 and 6.9.13-44, Magick frees the memory of the XML tree via the `DestroyXMLTree()` function; however, this process is executed recursively with no depth limit imposed. When Magick processes an XML file with deeply nested structures, it will exhaust the stack memory, resulting in a Denial of Service (DoS) attack. This issue has been fixed in versions 6.9.13-44 and 7.1.2-19.

Affected products

• ImageMagick: before 6.9.13-44; from 7.0.0-0 before 7.1.2-19 — fixed in 6.9.13-44, 7.1.2-19

How to fix

Upgrade to a fixed version: ImageMagick 6.9.13-44, 7.1.2-19. Check the vendor advisory for mitigations.
