Prototype Pollution

realms-shim is vulnerable to prototype pollution. An attacker is able to inject properties into existing construct prototypes and modify attributes such as proto, constructor, and prototype. and bypass the sandbox...

Sandbox Bypass

realms-shim is vulnerable to sandbox bypass. The vulnerability exists through the 'realmEvaluate' function in 'realm.js' as its does not properly validate the input, allowing an attacker bypass the sandbox by inject properties into existing construct prototypes...
