Description
This Pull Request patches a Critical Remote Code Execution (RCE) vulnerability in the execution engine.
The Vulnerability:
The default configuration (
UNSANDBOXEDmode) previously usednoOpCodeSandbox, which relies on theFunctionconstructor. This allowed user-supplied code to access the host processprocess.envand execute arbitrary commands.The Fix:
I have updated the
loadCodeSandboxfunction to mapUNSANDBOXEDandSANDBOXEDmodes toloadV8IsolateSandbox. This ensures that even in default configurations, user code is executed within a secure V8 Isolate, preventing unauthorized access to the host server.Type of Change
