- CWE-1321 Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')
- Fix
3.1.4- Upgrade dset to this version or later
Description
Versions of the package dset before 3.1.4 are vulnerable to Prototype Pollution via the dset function due improper user input sanitization. This vulnerability allows the attacker to inject malicious object property using the built-in Object property proto, which is recursively assigned to all the objects in the program.
Affected versions
npm
| Package | Vulnerable | Fixed in |
|---|---|---|
| dset | < 3.1.4 |
3.1.4 |
How to fix
Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.
dset npm → 3.1.4
- npm
npm install dset@3.1.4- yarn
yarn add dset@3.1.4- pnpm
pnpm add dset@3.1.4

Weakness
CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')
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.
How to prevent it
- Implementation: By freezing the object prototype first (for example, Object.freeze(Object.prototype)), modification of the prototype becomes impossible.
- Architecture and Design: By blocking modifications of attributes that resolve to object prototype, such as proto or prototype, this weakness can be mitigated.
- Implementation: When handling untrusted objects, validating using a schema can be used.
- Implementation: By using an object without prototypes (via Object.create(null) ), adding object prototype attributes by accessing the prototype via the special attributes becomes impossible, mitigating this weakness.
- Implementation: Map can be used instead of objects in most cases. If Map methods are used instead of object attributes, it is not possible to access the object prototype or modify it.
