- [SERVER-128125 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-128125){:target="_blank"} **(CVE-2026-11933):** A **use-after-free** vulnerability was identified in MongoDB Server’s server-side JavaScript engine when converting `BSON` documents to JavaScript arrays. An authenticated user with read privileges who can execute server-side JavaScript (e.g., via `$where` or `$function`) may trigger access to freed memory, which could result in information disclosure from the `mongod` process memory or a denial of service through a server crash.

- [SERVER-125063 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-125063){:target="_blank"} **(CVE-2026-9740):** A vulnerability in the `BSON` validator allows an unauthenticated user to supply specially crafted input that could cause the `mongod` process to terminate unexpectedly, resulting in a denial-of-service condition.

- [SERVER-124959 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-124959){:target="_blank"} **(CVE-2026-9753):** A vulnerability in the `$_internalApplyOplogUpdate` aggregation stage allows an authenticated user to supply specially crafted input that could cause the server process to terminate unexpectedly.

- [SERVER-123440 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-123440){:target="_blank"} **(CVE-2026-9752):** Inserting specially crafted documents into a collection with a `2dsphere` index could cause the `mongod` process to terminate unexpectedly, leading to a server crash.

- [SERVER-123633 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-123633){:target="_blank"} **(CVE-2026-9750):** A vulnerability in query execution allows an authenticated user to create specially crafted documents that interfere with internal metadata processing. This can cause the server process to terminate unexpectedly and may result in incorrect query results.

- [SERVER-124031 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-124031){:target="_blank"} **(CVE-2026-9749):** Aggregation pipelines that use the internal `$exchange` stage with key-range partitioning can trigger an unexpected condition when processing large numbers of documents for a single key range. This can cause the server process to terminate unexpectedly.

- [SERVER-123951 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-123951){:target="_blank"} **(CVE-2026-9748):** Under specific conditions, using the internal `$_internalConvertBucketIndexStats` stage together with `$facet` can cause the `mongod` process to terminate unexpectedly.

- [SERVER-123918 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-123918){:target="_blank"} **(CVE-2026-9747):** A vulnerability triggered by using `fromRouter: true` together with `runtimeConstants.userRoles` can cause the `mongod` process to terminate unexpectedly.

- [SERVER-124190 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-124190){:target="_blank"} **(CVE-2026-9746):** A vulnerability in the use of `$changeStream`, `$_requestReshardingResumeToken`, and the exchange option can cause the `mongod` process to terminate unexpectedly. An authenticated user can trigger this behavior without requiring any special privileges.

### Medium severity

- [SERVER-123370 :octicons-link-external-16:](https://jira.mongodb.org/browse/SERVER-123370){:target="_blank"} **(CVE-2026-9751):** Percona Server for MongoDB no longer logs sensitive parameter values when they are modified using the runtime `setParameter` command. Previously, parameters such as `ldapQueryPassword` could be written to `mongod.log` in plain text, potentially exposing credentials.

This applies to all `setParameter` operations. Parameters marked as sensitive are automatically redacted from log output, and values associated with unrecognized parameter names are also redacted to prevent accidental exposure caused by typographical errors.
