CVE-2026-114655libmongocrypt builds requests to external key management services (AWS, Azure and GCP) by inserting values from key vault documents, KMS provider configuration and KMS... Executive summary A flaw in libmongocrypt, a library used to encrypt data with external key management services, lets a user with write access to the key vault collection alter requests sent to AWS, Azure and GCP key services. The advisory rates it Moderate with a CVSS v3.1 base score of 5.9 and recommends upgrading to version 1.21.1. Technical summary The weakness is CWE-74, improper neutralization of special elements in output used by a downstream component (injection). libmongocrypt inserts values from key vault documents, KMS provider configuration and KMS responses into request lines, headers and signed request bodies without validating or encoding them, so a user with write access to the key vault collection can add members to request bodies and token claims that the library signs with the application's credentials. Affected versions are stated as >= 1.0.0, < 1.21.1, and the patched version is 1.21.1. The CVSS vector is CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:L/A:N. The advisory does not state any workaround, and it gives no detection guidance or information on exploitation in the wild. Summaries are generated by AI from the linked advisory text. Confirm versions and fixes at the source.

CVE-2026-114650A flaw in the client-side encryption support of the MongoDB .NET/C# driver can cause data designated for client-side field-level encryption to be written without encryption Executive summary The advisory describes a flaw in the client-side encryption support of the MongoDB .NET/C# driver that can cause data meant for client-side field-level encryption to be written without encryption. It is fixed in the 3.13.0 release of the driver, which also addresses several other CVEs. The advisory does not state a severity rating, and the recommended action is to upgrade to version 3.13.0 after reviewing the listed behavior changes. Technical summary The CVE-2026-114650 item (CSHARP-6180) is described as plaintext exposure of encrypted fields caused by ANSI code-page corruption of the database name, which made databases with non-ASCII names fail to match schema map namespaces. The fix changes automatic encryption to pass the database name to libmongocrypt as UTF-8 instead of the Windows ANSI code page. The advisory does not state the attack vector, required privileges, or exploitation status. It does not give a CVSS score, and it does not state a workaround or detection guidance beyond upgrading to 3.13.0 and reviewing the behavior changes. The advisory lists the fixed release as 3.13.0 and does not name the affected version range for this specific CVE. Summaries are generated by AI from the linked advisory text.

CVE-2026-106434The explicit decryption component of MongoDB libmongocrypt can return an unrecognized encrypted payload unchanged instead of returning a decryption error From the advisory 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 affected application to process the supplied bytes as decrypted plaintext.

CVE-2026-106433Improper 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... From the advisory 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-2026-106429An integer underflow in the KMS endpoint-parsing logic of MongoDB libmongocrypt can cause an allocation failure that terminates the application process From the advisory 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 a KMS endpoint containing a colon after its path or query during key creation. The issue does not access memory outside its allocated bounds.
