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-2026-18707 1 Mongodb 1 Mongodb Server 2026-08-13 4.3 Medium
An issue in MongoDB Server could allow an authenticated user, including one with no assigned privileges, to cause the server process to terminate unexpectedly by submitting a specially formed aggregation command. This could result in a denial of service.
CVE-2026-18704 1 Mongodb 1 Mongodb Server 2026-08-13 6.5 Medium
An issue in MongoDB Server's aggregation framework could allow an authenticated user with only read privileges to perform write operations against collections they should not be able to modify. This is due to an internal-use aggregation stage being reachable by external clients without an appropriate authorization check on its embedded operations.
CVE-2026-18705 1 Mongodb 1 Mongodb Server 2026-08-13 6.5 Medium
An issue in MongoDB Server's Atlas Vector Search feature could allow an authenticated user with read access to one view to retrieve documents from a different, protected view over the same underlying collection. This is due to insufficient handling of certain user-supplied fields when constructing an internal request forwarded to the search process.
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-2026-18701 1 Mongodb 1 Mongodb Server 2026-08-13 6.5 Medium
An issue in MongoDB Server's query subsystem could allow an authenticated user with read privileges to cause the server process to terminate unexpectedly by submitting a specially formed query filter. This could result in a denial of service.
CVE-2026-18695 1 Mongodb 1 Mongodb Server 2026-08-12 6.5 Medium
An issue in MongoDB Server's handling of certain query predicates against time-series collections with a metaField could allow an authenticated user with write access to cause the server process to terminate unexpectedly, resulting in a denial of service.
CVE-2026-18692 1 Mongodb 1 Mongodb Server 2026-08-12 8.8 High
An issue in MongoDB Server's handling of timeseries bucket lifecycle could allow an authenticated user with write privileges to cause an internal reference to be used after the underlying memory has been freed. Subsequent operations could then result in a server crash or, potentially, execution of unintended code.
CVE-2026-18697 1 Mongodb 1 Mongodb Server 2026-08-12 7.5 High
An issue in MongoDB Server's aggregation framework could allow an unauthenticated party to cause a mongos (router) process to terminate unexpectedly by submitting a specially formed aggregation command. This could result in a denial of service, disrupting client connections routed through the affected mongos instance.
CVE-2026-18700 1 Mongodb 1 Mongodb Server 2026-08-12 6.5 Medium
An issue in MongoDB Server's geospatial validation could allow an authenticated user with write privileges to cause an internal reference to be used after the underlying memory has been freed, through concurrent operations against a collection using a certain type of validator. This could result in a server crash, leading to a denial of service.
CVE-2026-18699 1 Mongodb 1 Mongodb Server 2026-08-12 6.5 Medium
An issue in MongoDB Server's query planner could allow an authenticated user with read-level privileges to cause the server process to terminate unexpectedly by submitting a specially formed query against a collection with a text index. This could result in a denial of service, affecting connected clients and in-flight operations.
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-2026-18703 1 Mongodb 1 Mongodb Server 2026-08-12 4.2 Medium
An issue in MongoDB Server could allow a party with a valid client certificate and a corresponding user account to authenticate using a certificate-based authentication method, even when an administrator has configured the server to restrict authentication to other mechanisms. This could allow authentication through a method the administrator intended to disable.
