Insecure Deserialization in Mongodb

How Insecure Deserialization Manifests in Mongodb

Insecure deserialization in Mongodb environments typically occurs when applications accept serialized data from untrusted sources and deserialize it without proper validation. This vulnerability can manifest in several Mongodb-specific contexts.

One common scenario involves Mongodb's Extended JSON format, which supports rich data types like Date, ObjectId, and BinData. When applications use JSON.parse() or similar methods on user-supplied JSON that contains these extended types, they may inadvertently execute code if the deserialization process evaluates embedded JavaScript.
