How to Fix CVE-2021-21304

To remediate this vulnerability, upgrade all affected Dynamoose dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

dynamoose fixed: 2.7.0 
npm install dynamoose@2.7.0
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls dynamoose

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2021-21304, inspect your project dependencies using npm:

npm ls dynamoose

Analyze the terminal output to locate any version of Dynamoose in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 2.7.0), your application is affected.

Note: The npm ls dynamoose command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution'), where 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. In Dynamoose, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Impact In Dynamoose versions 2.0.0-2.6.0 there was a prototype pollution vulnerability in the internal utility method [`lib/utils/object/set.ts`](https://github.com/dynamoose/dynamoose/blob/master/lib/utils/object/set.ts). This method is used throughout the codebase for various operations throughout Dynamoose. We have not seen any evidence of this vulnerability being exploited. We do not believe this issue impacts v1.x.x since this method was added as part of the v2 rewrite. This vulnerability also impacts v2.x.x beta/alpha versions. ### Patches v2.7.0 includes a patch for this vulnerability. ### Workarounds We are unaware of any workarounds to patch this vulnerability other than upgrading to v2.7.0 or greater. ### References - Patch commit hash: 324c62b4709204955931a187362f8999805b1d8e ### For more information If you have any questions or comments about this advisory: * [Contact me](https://charlie.fish/contact) * [Read our Security Policy](https://github.com/dynamoose/dynamoose/blob/master/SECURITY.md) ### Credit - GitHub CodeQL Code Scanning
