A vulnerability was found in bson-objectid 1.3.0 on Node.js (JavaScript Library). It has been classified as critical. Affected is the function ObjectID. The manipulation with an unknown input leads to a privilege escalation vulnerability. CWE is classifying the issue as CWE-20. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was disclosed 12/11/2019. This vulnerability is traded as CVE-2019-19729 since 12/11/2019. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 12/12/2019).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
