CVE-2026-106431

An off-by-one error in the BSON bulk document writer in the MongoDB C Driver can write one zero byte immediately past a heap allocation when a document ends at a specific buffer boundary. An actor who can influence the size of documents serialized by an embedding application can corrupt adjacent...

CVE-2026-106438

An incorrect calculation in Decimal128 string parsing in the MongoDB C Driver can accept certain over-precision inputs containing leading zeros instead of rejecting them. This produces a value different from the supplied text. An actor who can provide a decimal string to an embedding application,...

CVE-2026-106437

The BSON buffer-reservation API in the MongoDB C Driver can record a length smaller than the five-byte BSON minimum. Later append or comparison operations can underflow unsigned length calculations and read or write outside the document buffer. An actor who can influence the length supplied by an...

CVE-2026-106428

An out-of-bounds read in SCRAM authentication response parsing in the MongoDB C Driver can read one byte beyond a fixed-size buffer when processing a malformed server-final message. A server or network intermediary able to provide this message before server-signature verification can cause the...

CVE-2026-106430

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...

CVE-2026-106430 Query and rename target confusion via embedded NUL truncation in MongoDB C++ Driver

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...

EUVD-2026-95155

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...

CVE-2026-106430

The MongoDB C++ Driver is vulnerable to query and rename target confusion due to embedded NUL truncation . The driver discards content following a NUL byte in specific field and collection names accepted by the collection API , leading to a discrepancy between how the driver and the calling appli...

CVE-2026-106438 Silent Decimal128 value corruption via incorrect exactness check in MongoDB C Driver

An incorrect calculation in Decimal128 string parsing in the MongoDB C Driver can accept certain over-precision inputs containing leading zeros instead of rejecting them. This produces a value different from the supplied text. An actor who can provide a decimal string to an embedding application,...

EUVD-2026-95154

An incorrect calculation in Decimal128 string parsing in the MongoDB C Driver can accept certain over-precision inputs containing leading zeros instead of rejecting them. This produces a value different from the supplied text. An actor who can provide a decimal string to an embedding application,...

CVE-2026-106438

The MongoDB C Driver contains a vulnerability in its Decimal128 string parsing logic. An incorrect calculation during exactness checks allows the driver to accept certain over-precision inputs containing leading zeros rather than rejecting them. This results in the creation of a numeric value tha...

CVE-2026-106437

The MongoDB C Driver contains an out-of-bounds read and write vulnerability within its BSON buffer-reservation API. The root cause is an integer underflow (CWE-191) that occurs when the API records a length smaller than the five-byte BSON minimum. Subsequent append or comparison operations can tr...

EUVD-2026-95153

The BSON buffer-reservation API in the MongoDB C Driver can record a length smaller than the five-byte BSON minimum. Later append or comparison operations can underflow unsigned length calculations and read or write outside the document buffer. An actor who can influence the length supplied by an...

CVE-2026-106437 Out-of-bounds read and write via undersized BSON buffer reservation in MongoDB C Driver

The BSON buffer-reservation API in the MongoDB C Driver can record a length smaller than the five-byte BSON minimum. Later append or comparison operations can underflow unsigned length calculations and read or write outside the document buffer. An actor who can influence the length supplied by an...

CVE-2026-106431 One-byte heap buffer overflow in BSON bulk document writer in MongoDB C Driver

An off-by-one error in the BSON bulk document writer in the MongoDB C Driver can write one zero byte immediately past a heap allocation when a document ends at a specific buffer boundary. An actor who can influence the size of documents serialized by an embedding application can corrupt adjacent...

EUVD-2026-95152

An off-by-one error in the BSON bulk document writer in the MongoDB C Driver can write one zero byte immediately past a heap allocation when a document ends at a specific buffer boundary. An actor who can influence the size of documents serialized by an embedding application can corrupt adjacent...

CVE-2026-106431

The MongoDB C Driver contains a one-byte heap buffer overflow in the BSON bulk document writer . An off-by-one error allows a zero byte to be written past a heap allocation when a document ends at a specific buffer boundary. This vulnerability can lead to process memory corruption or a process te...

CVE-2026-106428 Out-of-bounds read in SCRAM response parsing in MongoDB C Driver

An out-of-bounds read in SCRAM authentication response parsing in the MongoDB C Driver can read one byte beyond a fixed-size buffer when processing a malformed server-final message. A server or network intermediary able to provide this message before server-signature verification can cause the...

CVE-2026-106428

The MongoDB C Driver is vulnerable to an out-of-bounds read during SCRAM authentication response parsing . Specifically, processing a malformed server-final message can cause the driver to read one byte beyond a fixed-size buffer. A server or network intermediary capable of providing this message...
