Sandbox Breakout / Arbitrary Code Execution

Overview Versions of safer-eval prior to 1.3.4 are vulnerable to Sandbox Escape leading to Remote Code Execution. A payload using constructor properties can escape the sandbox and execute arbitrary code. For example, evaluating he string console.constructor.constructor'return process'.env prints...
