CVE-2026-106430 is fixed in mongo-cxx-driver on 1 platform by DEBIAN-CVE-2026-106430 (version 4.6.1-1), released October 16, 2026. It is not reported as exploited. Patch Radar priority: Routine.
The MongoDB C++ Driver discards content after an embedded NUL byte in certain field and collection names accepted by the collection API. This can cause the driver and the calling application to interpret the same name differently. An authenticated actor who can influence a name passed by an affected application can cause the application to read distinct values from an unintended field or rename an unintended collection. These operations use the application's existing database credentials.
