CVE-2026-82054

Name of the Vulnerable Software and Affected Versions MongoDB server (affected versions not specified)

Description A security issue exists in the JSON Pointer parser used during $jsonSchema query filter processing. When a find command contains a specially crafted $jsonSchema filter field, the parser fails to enforce adequate limits on iteration count or total allocation size, leading to significant memory amplification. Under concurrent request load, this cumulative memory consumption can exhaust the available heap memory, triggering the out-of-memory handler to terminate the mongod process and resulting in a denial of service for all connected clients.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
