CVE-2026-82054Uncontrolled Resource Consumption in MongoDB Server JSON Pointer Parser Leads to Denial of Service

Updated under an hour ago ()

Does this affect you?

It affects MongoDB Server and 1 other product. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

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.
