CVE-2026-18694 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 7.1 High
An issue in MongoDB Server's geospatial query processing could allow an authenticated user with write privileges to cause certain malformed geometry data to be stored and later processed without proper validation. Subsequent queries against this data could then result in the server accessing memory outside its intended bounds. This could result in a server crash (denial of service) and may expose a limited amount of server process memory.
CVE-2026-18693 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 7.6 High
An issue in MongoDB Server's handling of timeseries collections could allow an authenticated user with write privileges to cause an internal data structure to become inconsistent through certain document insertions. A subsequent insert into the affected bucket could then result in the server accessing memory outside its intended bounds, potentially causing a server crash (denial of service), exposure of limited memory contents, or memory corruption.
CVE-2026-18692 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 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-2026-18691 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 8.8 High
An issue in MongoDB Server's intra-cluster connection setup could allow a party with suitable network access to influence which authentication mechanism is used when one replica set member connects to another. Under certain conditions, this could cause the cluster's shared internal credential to be transmitted in a less-protected form, potentially allowing that credential to be recovered. If recovered, the credential could be used to authenticate as the internal superuser to nodes in the deployment.
CVE-2026-18690 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 8.1 High
An issue in MongoDB Server could allow an authenticated user with a limited database-scoped role to perform an action against protected system collections that their assigned privileges should not permit. This could result in critical system collections being dropped and recreated without proper authorization.
CVE-2026-18688 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 7.1 High
An issue in MongoDB Server's aggregation framework could allow an authenticated user to trigger an out-of-bounds memory read by providing a specially formed numeric parameter in a certain aggregation pipeline stage. This could result in a server crash (denial of service) and may potentially expose a limited amount of memory contents.
CVE-2026-18687 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 7.1 High
MongoDB Server's handling of a Queryable Encryption maintenance operation did not properly validate certain request parameters against the collection's encrypted field configuration before use. An authenticated user with readWrite privileges could submit a specially formed request that leads to a server crash or excessive internal writes, resulting in resource exhaustion and corruption of encrypted index data.
CVE-2026-82076 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-14 6.5 Medium
An integer overflow in the query planning component of MongoDB Server can allow an authenticated user with ordinary database-level read/write privileges to bypass an internal resource limit. Submitting a specially crafted query causes the server to consume memory without bound during query planning, and the resulting exhaustion terminates the server process. This may result in a denial of service affecting all databases served by the affected node.
CVE-2026-89099 1 Mongodb 1 Mongodb Server 2026-09-12 7.5 High
A race condition in the document value layer of MongoDB Server can allow concurrent server threads to operate on the same internal memory without synchronization, leading to memory corruption. An authenticated user holding ordinary read-write privileges on a database may be able to trigger this condition over the normal client protocol, resulting in server termination and potential corruption of process memory with user-influenced content. Successful use of this issue may impact the confidentiality, integrity, and availability of the affected server process.
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-2026-18710 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.
