What is CVE-2026-18694?

A vulnerability in MongoDB Server's geospatial query processing can be exploited by authenticated users with write privileges. By introducing malformed geometry data, these users may bypass validation checks. As a result, when the server processes this data, it can access memory regions outside its intended boundaries, potentially leading to a denial of service situation where the server may crash, and limited server memory could be exposed to unauthorized access.

Affected Version(s)

MongoDB Server 8.3.0 < 8.3.8

MongoDB Server 8.0 < 8.0.29

MongoDB Server 7.0 < 7.0.40
