How to Fix CVE-2019-1020013

To remediate this vulnerability, upgrade all affected Parse server 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-server fixed: 3.6.0 
npm install parse-server@3.6.0
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-server

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-1020013, inspect your project dependencies using npm:

npm ls parse-server

Analyze the terminal output to locate any version of Parse server in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.6.0), your application is affected.

Note: The npm ls parse-server 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-209: Generation of Error Message Containing Sensitive Information, where the product generates an error message that includes sensitive information about its environment, users, or associated data. In Parse server, 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

Versions of parse-server prior to 3.6.0 could allow an account enumeration attack via account linking. `ParseError.ACCOUNT_ALREADY_LINKED(208)` was thrown BEFORE the AuthController checks the password and throws a `ParseError.SESSION_MISSING(206)` for Insufficient auth. An attacker can guess ids and get information about linked accounts/email addresses. ### For more information If you have any questions or comments about this advisory, Open an issue in the [parse-server](https://github.com/parse-community/parse-server) [Parse Community Vulnerability Disclosure Program](https://github.com/parse-community/parse-server/blob/master/SECURITY.md)
