CVE-2026-47103 · Python StateMachine 3.0.0 < 3.2.0 RCE via SCXML eval() Injection
Cette page présente des faits issus de sources publiques. Consultez l’avis original avant toute mise à jour.
Python StateMachine versions 3.0.0 before 3.2.0 contains a remote code execution vulnerability that allows 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.
