- Fix
0.8.3- Upgrade @xmldom/xmldom to this version or later
Description
Withdrawn
This advisory has been withdrawn because the maintainers of @xmldom/xmldom and multiple third parties disputed the validity of the issue. Attempts to create or replicate a proof of concept have been unsuccessful.
Original Description
Impact
A prototype pollution vulnerability exists in the function copy in dom.js in the xmldom (published as @xmldom/xmldom) package.
Patches
Update to @xmldom/xmldom@~0.7.6, @xmldom/xmldom@~0.8.3 (dist-tag latest) or @xmldom/xmldom@>=0.9.0-beta.2 (dist-tag next).
Workarounds
None

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.
@xmldom/xmldom npm → 0.8.3
- npm
npm install @xmldom/xmldom@0.8.3- yarn
yarn add @xmldom/xmldom@0.8.3- pnpm

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.
