DescriptionCVE.org
Mongoose is a MongoDB object modeling tool designed to work in an asynchronous environment. Prior to 6.13.10, 7.8.10, 8.24.1, and 9.7.2, passing a user-controlled update such as MyModel.updateOne(filter, req.body) can exploit Mongoose update casting with a __proto__.x dotted path under $set. Schema.prototype.path and Schema.prototype._getPathType can treat inherited properties of schema.paths and schema.nested as schema types, allowing the casting process to set $fullPath and $parentSchemaDocArray on Object.prototype before throwing. This prototype pollution makes those properties visible on newly created objects and can cause application integrity and availability impacts. This issue is fixed in versions 6.13.10, 7.8.10, 8.24.1, and 9.7.2.
AnalysisAI
Prototype pollution in Mongoose's update casting mechanism allows remote attackers (PR:N per CVSS vector) to corrupt Object.prototype by embedding a __proto__-prefixed dotted key inside a $set operator in any update payload passed without sanitization to Mongoose update operations. All major Mongoose release lines are affected below versions 6.13.10, 7.8.10, 8.24.1, and 9.7.2, impacting Node.js application integrity and availability wherever the req.body-to-updateOne anti-pattern exists. …
