safe-eval Project safe-eval

The safe-eval module describes itself as a safer version of eval. By accessing the object constructors, un-sanitized user input can access the entire standard library and effectively break out of the sandbox.

All versions of the package safe-eval are vulnerable to Sandbox Bypass due to improper input sanitization. The vulnerability is derived from prototype pollution exploitation. Exploiting this vulnerability might result in remote code execution ("RCE"). **Vulnerable functions:** __defineGetter__, stack(), toLocaleString(), propertyIsEnumerable.call(), valueOf().

All versions of the package safe-eval are vulnerable to Prototype Pollution via the safeEval function, due to improper sanitization of its parameter content.
