What is CVE-2026-82054?
CVE-2026-82054 is a high-severity denial of service vulnerability in Mongodb Mongodb, published on 8 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
Weakness: CWE-770
