CVE-2026-18694
Full vulnerability record from the local CVENow database.
Description
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.

"value": "Un problema en el procesamiento de consultas geoespaciales del servidor MongoDB podría permitir que un usuario autenticado con privilegios de escritura cause que ciertos datos de geometría malformados se almacenen y luego se procesen sin la validación adecuada. Las consultas posteriores contra estos datos podrían entonces resultar en que el servidor acceda a memoria fuera de sus límites previstos. Esto podría resultar en una caída del servidor (denegación de servicio) y podría exponer una cantidad limitada de memoria del proceso del servidor."
