In versions 1.39.2 and below, when parsing an MTLX file with multiple nested nodegraph implementations, the MaterialX XML parsing logic can potentially crash due to stack exhaustion. An attacker could intentionally crash a target program that uses OpenEXR by sending a malicious MTLX file. This is fixed in version 1.39.3.<\/div>\n<\/div>\n<div style=\"padding: 15px; border-radius: 5px; margin-bottom: 20px;\">\n<h4 style=\"margin-top: 0; \">References<\/h4>\n<ul style=\"margin: 0; padding-left: 20px;\">\n<li><a href=\"https:\/\/github.com\/AcademySoftwareFoundation\/MaterialX\/security\/advisories\/GHSA-wx6g-fm6f-w822\" target=\"_blank\">https:\/\/github.com\/AcademySoftwareFoundation\/MaterialX\/security\/advisories\/GHSA-wx6g-fm6f-w822<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/AcademySoftwareFoundation\/MaterialX\/issues\/2504\" target=\"_blank\">https:\/\/github.com\/AcademySoftwareFoundation\/MaterialX\/issues\/2504<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/AcademySoftwareFoundation\/MaterialX\/pull\/2505\" target=\"_blank\">https:\/\/github.com\/AcademySoftwareFoundation\/MaterialX\/pull\/2505<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/AcademySoftwareFoundation\/MaterialX\/releases\/tag\/v1.39.3\" target=\"_blank\">https:\/\/github.com\/AcademySoftwareFoundation\/MaterialX\/releases\/tag\/v1.39.3<\/a><\/li>\n<li><a href=\"https:\/\/github.com\/ShielderSec\/poc\/tree\/main\/CVE-2025-53009\" target=\"_blank\">https:\/\/github.com\/ShielderSec\/poc\/tree\/main\/CVE-2025-53009<\/a><\/li>\n<\/ul>\n<\/div>\n<div style=\"text-align: center; margin-top: 30px;\">\n<a href=\"\" target=\"_blank\" style=\"display: inline-block; background-color: #4CAF50; color: white; padding: 12px 24px; text-decoration: none; border-radius: 4px; font-weight: bold; transition: background-color 0.3s;\">View Full CVE Details<\/a>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>CVE Details Basic Information Title MaterialX Stack Overflow via Lack of MTLX XML Parsing Recursion Limit Type cve Published 2025-08-01T17:57:56.221Z Modified 2025-08-01T18:22:16.665Z Product Information Vendor&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[2],"tags":[6,8,70,12,21,13,7,11,5],"class_list":["post-9527","post","type-post","status-publish","format-standard","hentry","category-category_cve","tag-cve","tag-cvss","tag-cvss-55","tag-exploit","tag-medium","tag-news","tag-security","tag-tapic","tag-vulnerability"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
