CVE Vendors Products Updated CVSS v3.1
CVE-2026-18704 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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 2026-08-11 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-2026-18666 2026-08-11 4.3 Medium
The Library Management System WordPress plugin before 3.6.7 does not sanitize and escape a user-supplied parameter before using it in a SQL statement, allowing users with a role as low as Subscriber to perform SQL injection and extract arbitrary data from the database, including user password hashes.
CVE-2026-18469 2026-08-11 8.1 High
The Login & Register Forms WordPress plugin before 4.0.2 does not enforce its password reset attempt limit against a server-derived value, keying both the verification code and the per-source attempt counter on client-controlled data, allowing unauthenticated attackers to reset the limit at will and brute-force the code to take over any account, including administrators, when the verification-code reset mode is enabled.
CVE-2026-18468 2026-08-11 8.1 High
The Login & Register Forms WordPress plugin before 4.0.2 does not bind the password reset verification state to the account being reset or to the party that completed the verification, keying it instead on a value the client controls, allowing unauthenticated attackers to take over the account of any user who recently completed a reset verification, including an administrator.
