The MongoDB C# Driver writes GeoJSON extra members without checking whether their names collide with reserved GeoJSON members such as type and coordinates. An application that places user-supplied field names into these extra members can store documents with duplicate geometry fields, so the server and the driver resolve different values for the same record. Affected records can also become unreadable through the driver, interrupting application code that reads them.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
