How to Fix CVE-2019-19729

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

bson-objectid fixed: Latest secure release 
npm install bson-objectid@Latest secure release
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 bson-objectid

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2019-19729, inspect your project dependencies using npm:

npm ls bson-objectid

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

Note: The npm ls bson-objectid 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-20: Improper Input Validation, where the product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. In Bson objectid, 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

An issue was discovered in the BSON ObjectID (aka bson-objectid) package 1.3.0 for Node.js. ObjectID() allows an attacker to generate a malformed objectid by inserting an additional property to the user-input, because bson-objectid will return early if it `detects _bsontype==ObjectID` in the user-input object. As a result, objects in arbitrary forms can bypass formatting if they have a valid bsontype.
