CVE-2026-84969

A memory-handling error in the BSON-to-JSON conversion helpers of the MongoDB C Driver can write a small number of bytes past the end of a heap buffer when a binary field is encoded and the output is cut short at a caller-configured length limit. A party who supplies the document content, with no...

CVE-2026-84969

CVE-2026-84969 is a heap buffer overflow in the BSON-to-JSON conversion helpers of the MongoDB C Driver . The root cause is a truncated Base64 encoding of a binary field when the output is cut short at a caller-configured length limit, causing a small number of bytes to be written past the end of...

EUVD-2026-70505

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-2026-84970

A numeric truncation (32-bit length truncation) in the JSON parsing component of the MongoDB C++ Driver's BSON library allows a local attacker to supply an oversized JSON string to the library's public parsing interface, causing a heap over-read (out-of-bounds memory returned to the caller), a si...

Heap over-read or silent misparse via 32-bit truncation of JSON length in BSON JSON parser

SUSE CVE-2026-81524

A weakness in the MongoDB C Driver allows special elements in caller-supplied database and collection name components to pass without sanitization when the driver composes the target namespace for an operation. An application that incorporates untrusted input into these name components can have...

Linux Distros Unpatched Vulnerability : CVE-2026-81522

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A weakness in the MongoDB C++ Driver's handling of caller-supplied namespace identifiers allows special characters embedded in those identifiers. An application...

The vulnerability of the integration module with the Cyrus SASL library for interacting with MongoDB databases. The C driver allows a hacker to cause a service failure.

The vulnerability of the integration module with the Cyrus SASL library for interacting with MongoDB databases involves copying buffers without checking the size of the input data. Exploiting this vulnerability can allow an attacker to cause service failures...

CVE-2026-81530

A weakness in the client-side encryption configuration surface of the MongoDB C Driver causes sensitive key-management credential material supplied by the application to be reproduced verbatim in the driver's human-readable diagnostic representation of its client settings, instead of being masked...

CVE-2026-81527

A NoSQL/expression injection weakness exists in the LINQ-to-aggregation query translation layer of the MongoDB C Driver, in both aggregation expression and query filter translation. When application-supplied values are embedded in certain query constructs, special elements contained within those...

CVE-2026-81528

A MongoDB C driver document-replacement code path omits the element-name/shape validation that the equivalent write paths apply, so a value supplied as a replacement is forwarded to the server without neutralization of query-language special elements. An application that passes untrusted,...
