CVE-2026-84963 is fixed in mongo-c-driver on 1 platform by DEBIAN-CVE-2026-84963 (version 2.5.2-1), released September 10, 2026. It is not reported as exploited. Patch Radar priority: Routine.
An incorrect numeric conversion in the JSON parsing component of the MongoDB C Driver's BSON library may cause an unusually large text value to be silently shortened, or the corresponding field to be omitted, while the parsing operation still reports success and returns no error. An unauthenticated party who can supply the input processed by an application that uses this component may cause that application to hold data that does not match what was submitted, which may result in unintended alteration of data.
