Summary
The MongoDB C# Driver's BSON library is affected when an application deserializes untrusted content. An unauthenticated remote attacker who can supply such content can cause memory use to grow without limit, exhausting available memory and denying service to the application.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
The MongoDB C# Driver's BSON library contains an uncontrolled resource consumption weakness in its deserialization handling of one BSON value type. An application that deserializes untrusted content with the library retains data derived from that content for the lifetime of the process, with no limit on how much accumulates. An unauthenticated remote party who can cause such content to be deserialized can drive unbounded memory growth, exhausting the host application's available memory and denying service. There is no impact to confidentiality or integrity, and no MongoDB server component is affected.
