| CVE-2026-106433 | Hig | 0.57 | 8.8 | 0.00 | Oct 8, 2026 | Improper state management in MongoDB libmongocrypt can cause provider-specific data to be treated as an incompatible type when cleaning up a key document containing duplicate masterKey fields. An authenticated actor who can modify key vault documents, or a server that returns… | ||
| CVE-2026-106429 | Med | 0.42 | 6.5 | 0.00 | Oct 8, 2026 | An integer underflow in the KMS endpoint-parsing logic of MongoDB libmongocrypt can cause an allocation failure that terminates the application process. This can occur when an authenticated user modifies a key document in the key vault collection, or when an application accepts… | ||
| CVE-2026-84971 | Med | 0.42 | 6.5 | 0.00 | Sep 3, 2026 | Improper handling of an unexpected value size in the decryption path of a client-side encryption library can cause a failed internal check that terminates the process using the library. A party able to place a suitably formed encrypted value where an application will decrypt it,… | ||
| CVE-2026-114655 | Med | 0.31 | 5.9 | 0.00 | Oct 22, 2026 | libmongocrypt builds requests to external key management services (AWS, Azure and GCP) by inserting values from key vault documents, KMS provider configuration and KMS responses into request lines, headers and signed request bodies without validating or encoding them for each… | ||
| CVE-2026-106434 | Med | 0.28 | 4.3 | 0.00 | Oct 8, 2026 | The explicit decryption component of MongoDB libmongocrypt can return an unrecognized encrypted payload unchanged instead of returning a decryption error. An actor who can modify stored encrypted fields, such as a database writer, server, or network intermediary, can cause an… | ||
| CVE-2026-13063 | Med | 0.28 | 4.3 | 0.00 | Jul 22, 2026 | An authenticated user with standard read/write privileges can cause the mongod process to terminate due to an out-of-memory condition by sending a crafted aggregation command. MongoDB's libmongocrypt library insufficiently validates payload-supplied values, which can result in… | ||
| CVE-2026-84962 | Med | 0.27 | 4.2 | 0.00 | Sep 3, 2026 | An unauthorized user with key vault write access may cause an authorized client to issue arbitrary authenticated Google Cloud KMS API calls under the authorized user's identity, escalating database-level access into cloud key control and defeating client-side encryption. | ||
| CVE-2026-93394 | Low | 0.24 | 3.7 | 0.00 | Sep 17, 2026 | A flaw in libmongoc's SCRAM authentication implementation caused the client to continue the authentication handshake and transmit the client proof even when a nonce mismatch was detected in the server's first message. An unauthorized party with a man-in-the-middle position could… | ||
| CVE-2026-81523 | Med | 0.22 | 4.4 | 0.00 | Aug 27, 2026 | A missing input-validation issue in MongoDB libmongocrypt's automatic-encryption context setup allows a caller-supplied database identifier to be accepted without sanitization. The resulting impact is limited to incorrect schema selection, which may lead to limited disclosure or… |
