| CVE-2026-9751 | MÉDIO5.5 | The ldapQueryPassword parameter, when set through the runtime setParameter command, will log the new password to the mongod.log file in plain text. | 09/06/2026 |
| CVE-2026-9750 | MÉDIO6.5 | An authenticated user can cause a MongoDB server to crash or return incorrect results by creating documents that interfere with internal metadata processing during query execution. This stems from insufficient separation between user-controlled document fields and internal metadata in certain execution paths. | 09/06/2026 |
| CVE-2026-9749 | MÉDIO6.5 | This issue can occur when running an aggregation pipeline that uses the internal $exchange stage configured with key-range partitioning and order-preserving delivery. If a single key range produces enough documents to fill its exchange buffer (that is, many results are routed to the same consumer), the server reaches t | 09/06/2026 |
| CVE-2026-9748 | MÉDIO6.5 | The $_internalConvertBucketIndexStats stage used PauseExecution as a way to signal "skip this document" when an index stats conversion failed. But PauseExecution is not a general purpose skip mechanism, but rather a TeeBuffer-internal signal used solely by $facet to coordinate its sub-pipelines. When this stage is plac | 09/06/2026 |
| CVE-2026-9747 | MÉDIO6.5 | Adding fromRouter:true and runtimeConstants.userRoles could cause aggregations to crash mongodb server. | 09/06/2026 |
| CVE-2026-9746 | MÉDIO6.5 | When using $changestreams and $_requestReshardingResumeToken with the exchange option the server hits an invariant which causes the server to crash. There are no special privileges needed. The user must be logged in to issue the statement. | 09/06/2026 |
| CVE-2026-9743 | MÉDIO6.5 | In MongoDB Server 8.0, an aggregation stage can leave its _subPipeline field null during processing of certain pipelines. If a getMore is subsequently issued on the same cursor, the server may dereference this null sub-pipeline when reattaching to the operation context, accessing an invalid address and crashing the pro | 09/06/2026 |
| CVE-2026-9742 | MÉDIO5.9 | When OIDC authentication is enabled in configuration, clients may set specific values in the "mechanism" parameter of the "authenticate" command that lead to server crash. The authenticate command is accessible to unauthenticated clients, leading to pre-auth denial-of-service in affected product configurations. | 09/06/2026 |
| CVE-2026-9741 | MÉDIO6.5 | A bug in query analysis processing of the $vectorSearch aggregation stage for Queryable Encryption (QE) or Client-Side Field Level Encryption (CSFLE) results in literal values for encrypted fields within the $vectorSearch stage filter expressions to be sent to the server as plaintext instead of ciphertext. | 09/06/2026 |
| CVE-2026-9740 | ALTO7.5 | A vulnerability in MongoDB Server's BSON validation logic allows an unauthenticated user to crash the mongod process by sending a specially crafted message. The BSON validator's handling of certain nested binary data structures permits uncontrolled mutual recursion between validation functions, where each re-entry rese | 09/06/2026 |
| CVE-2026-9735 | MÉDIO5.5 | MongoDB server may log authentication parameters, including credentials, to the server log during SASL authentication. When connection health metric logging is enabled, the full authentication parameters are written to the log without redaction. | 09/06/2026 |
| CVE-2026-9101 | MÉDIO4.3 | Prototype pollution in csv parsing logic during import can lead to untrusted file paths (but not arguments) entering shell.openExternal after specific user behavior leading to "1-click" command execution. | 20/05/2026 |
| CVE-2026-9100 | ALTO7.1 | The MongoDB C Driver's legacy GridFS API accepts malformed file metadata from the database without adequate validation. Crafted documents in a GridFS collection may cause any application that reads those files via the legacy API to either crash (via a division-by-zero) or silently leak process memory contents (via an o | 20/05/2026 |
| CVE-2026-8843 | MÉDIO6.5 | Creating a "2dsphere_bucket" index on a non-timeseries bucket collection will succeed, but any subsequent attempt to insert a document which triggers updating that index will crash the server. A similar issue occurs when creating "queryable_encrypted_range" indices.

| CVE-2026-6811 | ALTO7.5 | Stack exhaustion vulnerability in the MongoDB PHP driver can cause application crashes when processing deeply nested BSON documents in unusual circumstances when the source of these BSON documents is not MongoDB Server. | 14/05/2026 |
| CVE-2026-8336 | MÉDIO6.5 | After invoking $_internalJsEmit, which is not intended to be directly accessible, or mapreduce command’s map function in a certain way, an authenticated user can subsequently crash mongod when the server-side JavaScript engine (through $where, $function, mapreduce reduce stage, etc.) is used also in a specific way, res | 13/05/2026 |
| CVE-2026-8202 | MÉDIO6.5 | Using a densely populated chars mask and a large input string in the MongoDB aggregation operators $trim, $ltrim, and $rtrim, an authenticated user with aggregation permissions can pin CPU utilization at 100% for an extended period of time.
