## Description

A security issue exists in MongoDB server's JSON Pointer parser used during $jsonSchema query filter processing. When a find command includes a specially crafted $jsonSchema filter field, the parser processes the input without enforcing adequate limits on iteration count or total allocation size, resulting in significant memory amplification. Under concurrent request load, the cumulative memory consumption can exhaust available heap memory, causing the server's out-of-memory handler to terminate the mongod process and deny service to all connected clients.

## Affected Products

- MongoDB — MongoDB Server (8.3.0)
- MongoDB — MongoDB Server (8.0.0)
- MongoDB — MongoDB Server (7.0.0)
