Disclosure summary
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 `` 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.

GitHub repository matches
Repository matches are links and GitHub-supplied metadata only. They are not verified working proof-of-concept code. Each supported query is bounded to ten pages and at most 1,000 indexed results. This is not a complete index of GitHub or public exploit research. Coverage can also be limited by provider availability, rate limits, rejected metadata, incomplete search results, manual review, and the recorded refresh time.
