vm2 is vulnerable to Information Disclosure
58
Medium Risk
This Affects:
vm2TL;DR
vm2 formats error stacks on the host side and forwards .stack reads from the sandbox bridge back to sandboxed code without redaction. Passing malformed source to eval() triggers a host-side SyntaxError whose stack is returned to the sandbox. Sandboxed code reads absolute host filesystem paths, internal Node details, and embedding-application source locations even under default VM and NodeVM configurations. The fix redacts sensitive path information from stack formatting before it reaches the sandbox.
