CVE-2026-106433 1 Mongodb 1 Libmongocrypt 2026-10-27 N/A 8.8 HIGH
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 such a key document, can cause invalid memory access and invalid frees in the client process. This can terminate the application or corrupt process memory.
CVE-2026-84962 1 Mongodb 1 Libmongocrypt 2026-09-17 N/A 4.2 MEDIUM
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-2026-81523 1 Mongodb 1 Libmongocrypt 2026-09-17 N/A 4.4 MEDIUM
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 modification of information handled by the application.
CVE-2026-84971 1 Mongodb 1 Libmongocrypt 2026-09-17 N/A 6.5 MEDIUM
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, or able to control the responses the application receives, may cause that application to stop running.
