CVE-2026-84963

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 unauthenticat...

CVE-2026-84965

An integer wraparound in an allocation size calculation in the BSON library's JSON parsing code can cause a buffer to be released while a following copy operation still writes through the stale pointer. On builds where sizes are 32 bits, an unauthenticated party able to supply a sufficiently larg...

CVE-2026-84970

A numeric truncation weakness exists in the JSON parsing component of the MongoDB C++ Driver's BSON library. An actor who controls the text that an embedding application hands to the library's public JSON parsing interface, when that text is very large, can cause the library to read memory beyond...

CVE-2026-84965

CVE-2026-84965 affects the BSON library within the MongoDB C Driver (tracked as CDRIVER-6405 ). An integer wraparound in an allocation size calculation during JSON parsing can cause a buffer to be freed while a subsequent copy still writes through the stale pointer (use-after-free). This is explo...

CVE-2026-13077 Out-of-Bounds Heap Read in BSON CodeWScope Element Parsing via Malformed BSONColumn Data

A missing bounds check in the BSON CodeWScope element accessors allows an attacker to trigger an out-of-bounds heap read via a crafted aggregation pipeline. The vulnerability can be exploited by an authenticated user by generating a malformed BSONColumn data containing a CodeWScope element,...

BIT-MONGODB-2025-0755 MongoDB C Driver bson library may be susceptible to buffer overflow

The various bsonappend functions in the MongoDB C driver library may be susceptible to buffer overflow when performing operations that could result in a final BSON document which exceeds the maximum allowable size INT32MAX, resulting in a segmentation fault and possible application crash. This...
