Threats affecting pkg:npm/mongoose

A prototype pollution vulnerability exists in Automattic's mongoose before versions 6.13.10, 7.8.10, 8.24.1, and 9.7.2. The issue arises when user-controlled updates with a __proto__.x dotted path under $set are passed to update functions, allowing modification of Object.prototype properties. This can affect application integrity and availability. The vulnerability has a CVSS score of 6.5 (medium severity).

Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Prior to 6.13.9, 7.8.9, 8.22.1, and 9.1.6, a 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 injected inside a $nor clause without being sanitized. This vulnerability is fixed in 6.13.9, 7.8.9, 8.22.1, and 9.1.6.

Mongoose before 8.9.5 can improperly use a nested $where filter with a populate() match, leading to search injection. NOTE: this issue exists because of an incomplete fix for CVE-2024-53900.

Mongoose before 8.8.3 can improperly use $where in match, leading to search injection.
