EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under NVD CVSS v3. EPSS exploit probability: 0.6%, top 55% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

MaterialX is an open standard for the exchange of rich material and look-development content across applications and renderers. 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.
