PYSEC-2026-1609 MaterialX Stack Overflow via Lack of MTLX XML Parsing Recursion Limit

Summary When parsing an MTLX file with multiple nested nodegraph implementations, the MaterialX XML parsing logic can potentially crash due to stack exhaustion. Details By specification, multiple kinds of elements in MTLX support nesting other elements, such as in the case of nodegraph elements...

PYSEC-2026-1608 MaterialX Lack of MTLX Import Depth Limit Leads to DoS (Denial-Of-Service) Via Stack Exhaustion

Summary Nested imports of MaterialX files can lead to a crash via stack memory exhaustion, due to the lack of a limit on the "import chain" depth. Details The MaterialX specification supports importing other files by using XInclude tags. When parsing file imports, recursion is used to process...

MaterialX Null Pointer Dereference in getShaderNodes due to Unchecked nodeGraph->getOutput return

SummaryWhen parsing shader nodes in a MTLX file, the MaterialXCore code accesses a potentially null pointer, which can lead to crashes with maliciously crafted files. DetailsIn src/MaterialXCore/Material.cpp, in function getShaderNodes, the following code fetches the output nodes for a given...
