Advisories for Npm/Mongoose package

What kind of vulnerability is it? Who is impacted? Prototype pollution in update casting: passing a user-controlled update to a Mongoose update, like MyModel.updateOne(filter, req.body), can cause Mongoose to set $fullPath and $parentSchemaDocArray on Object.prototype. Example: const mongoose = require('mongoose'); console.log('before:', Object.prototype.$fullPath); // undefined const User = mongoose.model('User', new mongoose.Schema({ name: String })); const malicious = JSON.parse('{"$set": {"proto.x": "anything"}}'); // attacker-controlled update const q = User.updateOne({}, {}); try { q._castUpdate(malicious); …

This vulnerability allows bypassing Mongoose’s sanitizeFilter query sanitization mechanism via the $nor operator. When sanitizeFilter is enabled, Mongoose wraps query operators in $eq to neutralize them. However, prior to the fix, $nor was not included in the set of logical operators that are recursively sanitized. Because $nor accepts an array (like $and and $or), and arrays do not trigger hasDollarKeys(), malicious operators such as $ne, $gt, or $regex could be …

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.

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.

Prototype Pollution in GitHub repository automattic/mongoose prior to 7.3.4.

This advisory has been marked as False Positive as it is a duplicate of CVE-2022-2564

Prototype Pollution in GitHub repository automattic/mongoose prior to 6.4.6.

Versions of mongoose before 4.3.6, 3.8.39 are vulnerable to remote memory exposure. Trying to save a number to a field of type Buffer on the affected mongoose versions allocates a chunk of uninitialized memory and stores it in the database. Recommendation Update to version 4.3.6, 3.8.39 or later.

Automattic Mongoose allows attackers to bypass access control (in some applications) because any query object with a _bsontype attribute is ignored.
