      "value": "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."

Esto puede permitir a un atacante a\u00f1adir/modificar propiedades del Object.prototype conllevando a una vulnerabilidad de contaminaci\u00f3n del prototipo. **Nota:** Esta vulnerabilidad puede ocurrir de m\u00faltiples maneras, por ejemplo cuando es modificada una colecci\u00f3n con una entrada de usuario no confiable"
