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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P","score":5.5},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-121"],"references":["https://github.com/AcademySoftwareFoundation/MaterialX/issues/2504","https://github.com/AcademySoftwareFoundation/MaterialX/pull/2505","https://github.com/AcademySoftwareFoundation/MaterialX/releases/tag/v1.39.3","https://github.com/AcademySoftwareFoundation/MaterialX/security/advisories/GHSA-wx6g-fm6f-w822","https://github.com/ShielderSec/poc/tree/main/CVE-2025-53009"],"products":["linuxfoundation:materialx"],"source":"nvd","synced_at":"2026-10-19T22:05:46.678065081+00:00"},"epss":{"cve":"CVE-2025-53009","score":0.00665,"percentile":0.51808,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-wx6g-fm6f-w822","url":"https://osv.dev/vulnerability/GHSA-wx6g-fm6f-w822","summary":"MaterialX Stack Overflow via Lack of MTLX XML Parsing Recursion Limit ","modified":"2026-07-07T17:56:59.752328778Z","packages":[{"ecosystem":"PyPI","name":"materialx","purl":"pkg:pypi/materialx","ranges":[">=1.39.2 <1.39.3"],"fixed":["1.39.3"]}]},{"id":"PYSEC-2026-1609","url":"https://osv.dev/vulnerability/PYSEC-2026-1609","summary":"MaterialX Stack Overflow via Lack of MTLX XML Parsing Recursion Limit ","modified":"2026-07-07T17:47:03.413946389Z","packages":[{"ecosystem":"PyPI","name":"materialx","purl":"pkg:pypi/materialx","ranges":[">=1.39.2 <1.39.3"],"fixed":["1.39.3"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
