CVE-2026-81527 1 Mongodb 1 C# Driver 2026-08-28 6.5 Medium
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 values are not properly escaped before the resulting query is transmitted to the database, so portions of the value may be interpreted by the database as query logic rather than as data. A user able to supply values that an application incorporates into an affected query may thereby cause unintended data to be returned or query results to be altered.
CVE-2026-81528 1 Mongodb 1 C# Driver 2026-08-28 5.4 Medium
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, loosely-typed input as a replacement value therefore allows that input to be interpreted by the database as update logic rather than as data, executing under the application's own database credentials. Applications using strongly-typed document mappings are not affected.
CVE-2026-81530 1 Mongodb 1 C# Driver 2026-08-28 5.6 Medium
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 as other secret fields are. A party able to read the application's logs, diagnostic output, or a process memory dump may thereby recover the plaintext credentials and use them to decrypt protected field data.
CVE-2026-13071 1 Mongodb 2 Mongodb, Mongodb Server 2026-08-18 6.5 Medium
An authenticated user with read access can cause the mongod process to be terminated through certain aggregation expressions that execute server-side JavaScript. The issue involves improper memory handling during document processing.
CVE-2026-13072 1 Mongodb 2 Mongodb, Mongodb Server 2026-08-18 8.1 High
When compute mode is enabled on a standalone mongod instance, insufficient validation of externally sourced BSON data during aggregation pipeline processing can result in memory corruption, potentially leading to process termination or other unintended behavior. This configuration is non-default and requires explicit enablement at startup.
CVE-2026-13073 1 Mongodb 2 Mongodb, Mongodb Server 2026-08-18 4.3 Medium
An authenticated user with read-only privileges can cause the mongod process to terminate abnormally by issuing a crafted aggregation command, resulting in denial of service for all connected clients until the process is restarted. The issue stems from an internal engine selection inconsistency triggered by a specific combination of aggregation options.
CVE-2026-13074 1 Mongodb 2 Mongodb, Mongodb Server 2026-08-18 5.3 Medium
An unauthenticated remote client can cause excessive CPU consumption on a MongoDB server by sending a specific combination of parameters to the awaitable hello command in exhaust mode. The server's handling of this combination results in a response loop that bypasses normal throttling, allowing a small number of connections to degrade server availability.
CVE-2026-13075 1 Mongodb 2 Mongodb, Mongodb Server 2026-08-18 6.5 Medium
An authenticated user can cause the mongod process to be terminated by the operating system under memory pressure via the $rankFusion and $scoreFusion aggregation stages. The issue originates in the server's error-handling path and requires the ability to run aggregation queries.
CVE-2026-13076 1 Mongodb 2 Mongodb, Mongodb Server 2026-08-18 6.5 Medium
An authenticated user can cause a {{mongod}} process to be terminated by the operating system under memory pressure by performing a specific data type conversion operation within MongoDB's aggregation framework. The behavior stems from disproportionate memory consumption during this operation, and requires both write access to the database and the ability to run aggregation queries.
CVE-2026-13077 1 Mongodb 2 Mongodb, Mongodb Server 2026-08-18 7.1 High
A missing bounds check in the BSON CodeWScope element accessors allows an attacker to trigger an out-of-bounds heap read via a crafted aggregation pipeline. The vulnerability can be exploited by an authenticated user by generating a malformed BSONColumn data containing a CodeWScope element, bypassing wire-level BSON validation. When the forged element is decompressed, the unchecked size value is used in pointer arithmetic, causing either a server crash or disclosure of adjacent heap memory contents.
CVE-2026-13078 1 Mongodb 2 Mongodb, Mongodb Server 2026-08-18 7.7 High
A vulnerability was discovered in MongoDB Server where the server-side MozJS scripting engine unconditionally registered a module loading hook that enables JavaScript calls to read arbitrary files from the host filesystem using the mongod process's privileges. An authenticated user could exploit this through crafted aggregation pipeline commands to read sensitive files accessible to the MongoDB server process.
CVE-2026-19503 1 Mongodb 2 Atlas Sql Odbc Driver, Schema Builder Cli 2026-08-13 4.8 Medium
MongoDB Schema Manager and MongoDB Atlas SQL ODBC Driver do not validate the scheme of the authorization and token endpoints returned by an OIDC issuer's discovery document. A user induced to connect to an uncontrolled MongoDB deployment using MONGODB-OIDC authentication may have an uncontrolled URI dispatched to their operating system's default protocol handler, potentially exposing credentials or, under certain conditions, resulting in code execution in the user's context.
CVE-2026-19502 1 Mongodb 1 Schema Builder Cli 2026-08-13 5.5 Medium
MongoDB SQL Schema Builder CLI records its startup configuration to standard output and, when file logging is enabled, to a log file on disk. Certain connection settings were written without redaction, so authentication material supplied by the operator could appear in plaintext in that diagnostic output. A local user with read access to the terminal session or the log directory, or anyone with access to a location where those logs are subsequently collected, could obtain those values.
CVE-2026-18710 1 Mongodb 1 Mongodb Server 2026-08-13 6.5 Medium
A MongoDB driver component could write sensitive configuration information, including a credential used for outbound network connectivity, to application log output in cleartext during routine client initialization. This occurs automatically as part of normal operation and requires no special privileges to trigger. A party able to read the affected application's logs or downstream log-aggregation storage could recover the credential and reuse it to authenticate to the associated network infrastructure. This issue affects confidentiality only.
CVE-2026-18711 1 Mongodb 1 Mongodb Server 2026-08-12 7.1 High
An issue in MongoDB Server's query execution engine could allow an authenticated user with read and write privileges to cause an internal reference to be used after the underlying memory has been freed, when running certain queries against time-series collections. This could result in a server crash or disclosure of freed memory contents within query results.
CVE-2026-18712 1 Mongodb 1 Mongodb Server 2026-08-12 8.1 High
An issue in MongoDB Server's Queryable Encryption maintenance operations could allow an authenticated user with privileges on one encrypted collection to cause unauthorized modification or destruction of data belonging to a different collection. This is due to insufficient validation of certain internal metadata references before they are used to perform operations on other namespaces.
CVE-2026-13069 1 Mongodb 2 Mongodb, Mongodb Server 2026-07-27 6.5 Medium
An authenticated user can cause excessive CPU consumption or out-of-memory conditions on a MongoDB server by sending a crafted Queryable Encryption find payload containing an unvalidated field used to control an internal computation loop. The resulting resource exhaustion degrades availability for other operations.
CVE-2026-13056 1 Mongodb 2 Mongodb, Mongodb Server 2026-07-27 6.5 Medium
Using expressions that generate large arrays it is possible to craft a query that creates very large intermediate objects in memory, causing the server to crash with OOM error.
CVE-2026-14881 1 Mongodb 1 Compass 2026-07-24 7.8 High
When importing connections in Compass it is possible to override some connection options that are otherwise can't be changed via connection form. In particular it is possible to provide a custom browser open command for OIDC auth flow that is usually can be set only globally via Compass settings.
CVE-2026-13059 1 Mongodb 2 Mongodb, Mongodb Server 2026-07-24 8.1 High
An authenticated user with low privileges may be able to perform unauthorized reads and writes on data protected by role-based query-level access controls, due to insufficient validation of certain client-supplied command parameters. The issue affects find, update, delete, and aggregate commands in non-apiStrict configurations.
