CVE-2026-82052 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 6.5 Medium
The $regexFindAll expression can be used by an authenticated user who can run aggregation pipeline stages to crash a MongoDB server (mongod). Under certain specific conditions theĀ  regex match can start in the middle of a multi-code-unit character, triggering an assertion during query execution.
CVE-2026-82053 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 8.1 High
A security issue exists in MongoDB's LDAP authorization integration where pooled LDAP connections can retain stale authentication identities after user authentication under certain configurations. Subsequent authorization queries may execute under an unintended LDAP identity rather than the expected one. This can result in incorrect role assignments based on the LDAP directory's access control configuration, potentially allowing an authenticated user to acquire elevated privileges that were not intended by the deployment's authorization policy.
CVE-2026-82054 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 6.5 Medium
A security issue exists in MongoDB server's JSON Pointer parser used during $jsonSchema query filter processing. When a find command includes a specially crafted $jsonSchema filter field, the parser processes the input without enforcing adequate limits on iteration count or total allocation size, resulting in significant memory amplification. Under concurrent request load, the cumulative memory consumption can exhaust available heap memory, causing the server's out-of-memory handler to terminate the mongod process and deny service to all connected clients.
CVE-2026-82075 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 7.5 High
An uncontrolled resource consumption weakness exists in the request-handling path of the MongoDB sharded-cluster router process. A client that has network access to a router port and has not authenticated can supply connection-monitoring parameters that cause the server to expend CPU resources without any rate limiting, degrading or denying service to legitimate clients. No authentication, elevated privileges, or user interaction is required. Only availability is affected; data confidentiality and integrity are not impacted.
CVE-2026-18709 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 6.4 Medium
An issue in MongoDB Server could allow an authenticated user with direct network access to a shard to improperly commit or abort an in-progress prepared transaction, bypassing the intended transaction coordination process. This could result in cross-shard data inconsistency, cluster clock corruption, and violation of transaction atomicity guarantees.
CVE-2026-18708 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 6.4 Medium
An issue in MongoDB Server's JavaScript scripting engine could allow an authenticated user with write privileges to cause code they control to be executed within the query scope of other users, through a specially crafted stored value processed during an internal maintenance cycle. This could result in corruption of query results affecting other users and denial of service targeted at their operations on the same database. Impact is limited to the scripting engine's execution sandbox, which does not provide access to database, filesystem, or network resources.
CVE-2026-18707 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 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-2026-18706 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 6.6 Medium
An issue in MongoDB Server's $graphLookup aggregation stage could allow an authenticated user able to issue aggregation and memory-management commands to cause an internal reference to be used after the underlying memory has been freed. This could result in a server crash or, potentially, execution of unintended code.
CVE-2026-18705 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 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-2026-18704 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 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-2026-18703 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 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.
CVE-2026-18702 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 6.4 Medium
An issue in MongoDB Server could allow an authenticated user with limited, database-scoped privileges to modify diagnostic logging settings that affect the entire server rather than just the intended database. This could allow suppression of diagnostic logging server-wide, potentially obscuring unauthorized activity, or degrade operational monitoring by causing excessive log volume.
CVE-2026-18701 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 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-2026-18700 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 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 2 Mongodb, Mongodb Server 2026-09-16 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-2026-18698 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 5.4 Medium
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 should require more specific privileges. This could result in exposure of collection metadata and, on certain deployment configurations, unauthorized modification of system collection data.
CVE-2026-18697 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 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-2026-18696 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 6.5 Medium
An issue in MongoDB Server's applyOps command could allow an authenticated user with specific non-default privileges to perform certain data-definition operations, such as dropping or modifying collections, against collections they do not have permission to manipulate. This is due to an inconsistency in how the target collection is determined between the authorization check and the actual operation.
CVE-2026-18695 1 Mongodb 2 Mongodb, Mongodb Server 2026-09-16 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-2026-18694 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.
