attackers to execute arbitrary code by supplying malicious SCXML documents containing crafted `<data
expr="...">` attributes evaluated unsafely. The SCXMLProcessor passes attacker-controlled expression
strings through a call chain ending in Python's built-in eval() without sandboxing, enabling arbitrary
code execution in the context of the hosting process. (CVE-2026-47103)
