type: bug
From CodeQL: > Most JavaScript objects inherit the properties of the built-in Object.prototype object. Prototype pollution is a type of vulnerability in which an attacker is able to modify Object.prototype. > Since most objects inherit from the compromised Object.prototype object, the attacker can use this to tamper with the application logic, and often escalate to remote code execution or cross-site scripting. To fix the problem, we need to ensure that the `appId` cannot be used to modify the `Object.prototype`.

To fix the problem, we need to ensure that the
appIdcannot be used to modify theObject.prototype. This can be achieved by validating theappIdbefore using it as a key in the object assignment. We will reject anyappIdthat matches__proto__,constructor, orprototype.
