CVE-2026-18694
HighCVSS 7.1Exploitation Probability (EPSS)
Low risk19th percentile - higher than 19% of all known CVEs
Summary
A vulnerability in MongoDB Server's geospatial query processing allows an authenticated user with write privileges to store malformed geometry data that is later processed without proper validation. This can lead to out-of-bounds memory access, causing a server crash (denial of service) and potentially exposing a limited amount of server process memory.
Risk Assessment
The risk includes denial of service and potential memory disclosure, which could compromise confidentiality of server data.
Recommendation
Update MongoDB Server to a patched version and restrict write privileges to reduce the risk of exploitation.
Original NVD description (English source)
An issue in MongoDB Server's geospatial query processing could allow an authenticated user with write privileges to cause certain malformed geometry data to be stored and later processed without proper validation. Subsequent queries against this data could then result in the server accessing memory outside its intended bounds. This could result in a server crash (denial of service) and may expose a limited amount of server process memory.
