GitHub Vulnerability Alerts

CVE-2024-53900

Mongoose versions prior to 8.8.3, 7.8.3, and 6.13.5 are vulnerable to improper use of the $where operator. This vulnerability arises from the ability of the $where clause to execute arbitrary JavaScript code in MongoDB queries, potentially leading to code injection attacks and unauthorized access or manipulation of database data.

CVE-2025-23061

Mongoose versions prior to 8.9.5, 7.8.4, and 6.13.6 are vulnerable to improper use of the $where operator. This vulnerability arises from the ability of the $where clause to execute arbitrary JavaScript code in MongoDB queries, potentially leading to code injection attacks and unauthorized access or manipulation of database data.

NOTE: this issue exists because of an incomplete fix for CVE-2024-53900.

CVE-2022-2564

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Affected versions of this package are vulnerable to Prototype Pollution. The Schema.path() function is vulnerable to prototype pollution when setting the schema object. This vulnerability allows modification of the Object prototype and could be manipulated into a Denial of Service (DoS) attack.

CVE-2023-3696

Prototype Pollution in GitHub repository automattic/mongoose prior to 7.3.3, 6.11.3, and 5.13.20.

CVE-2022-24304

Description

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment.

Affected versions of this package are vulnerable to Prototype Pollution. The Schema.path() function is vulnerable to prototype pollution when setting the schema object. This vulnerability allows modification of the Object prototype and could be manipulated into a Denial of Service (DoS) attack.

Proof of Concept

// poc.js
const mongoose = require('mongoose');
const schema = new mongoose.Schema();

malicious_payload = '__proto__.toString'

schema.path(malicious_payload, [String])

x = {}
console.log(x.toString()) // crashed (Denial of service (DoS) attack)

Impact

This vulnerability can be manipulated to exploit other types of attacks, such as Denial of service (DoS), Remote Code Execution, or Property Injection.
