A critical vulnerability, identified as CVE-2026-33908, affects versions before 7.1.2-19 and 6.9.13-44. This vulnerability stems from the lack of depth limit during recursive processing of XML files via the \u003ccode\u003eDestroyXMLTree()\u003c/code\u003e function. An attacker can exploit this by crafting a malicious XML file with deeply nested structures. When ImageMagick parses this file, the recursive function exhausts stack memory, leading to a denial-of-service condition. Successful exploitation can disrupt services relying on ImageMagick, impacting image processing workflows.
