How to Fix CVE-2025-62374

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

parse fixed: 7.0.0 
npm install parse@7.0.0
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 parse

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-62374, inspect your project dependencies using npm:

npm ls parse

Analyze the terminal output to locate any version of Parse in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 7.0.0), your application is affected.

Note: The npm ls parse 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 Parse, 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

### Summary Prototype pollution capabilities on various APIs. ### Details Injection of malicious payload allows attacker to remotely execute arbitrary code. `Parse.Object` and internal APIs are affected, specifically: - `ParseObject.fromJSON` - `ParseObject.pin` - `ParseObject.registerSubclass` - `ObjectStateMutations` (internal) - `encode`/`decode` (internal) ### PoC Demonstrative tests added as part of the fix. ### References - https://github.com/parse-community/Parse-SDK-JS/security/advisories/GHSA-9f2h-7v79-mxw3 - Patch https://github.com/parse-community/Parse-SDK-JS/releases/tag/7.0.0-alpha.1
