Sandbox Breakout / Arbitrary Code Execution in @zhaoyao91/eval-in-vm
All versions of @zhaoyao91/eval-in-vm are vulnerable to Sandbox Escape leading to Remote Code Execution. The package fails to restrict access to the main context through this.constructor.constructor . This may allow attackers to execute arbitrary code in the system. Evaluating the payload this.constructor.constructor('return process.env')() prints the contents of process.env.
Recommendation
No fix is currently available. Consider using an alternative package until a fix is made available.
