The package dexie before 3.2.2, from 4.0.0-alpha.1 and before 4.0.0-alpha.3 are vulnerable to Prototype Pollution in the Dexie.setByKeyPath(obj, keyPath, value) function which does not properly check the keys being set (like proto or constructor). This can allow an attacker to add/modify properties of the Object.prototype leading to prototype pollution vulnerability. Note: This vulnerability can occur in multiple ways, for example when modifying a collection with untrusted user input.
The product receives input from an upstream component that specifies attributes that are to be initialized or updated in an object, but it does not properly control modifications of attributes of the object prototype.
