Detailsinfo

A vulnerability was found in MongoDB Server up to 7.0.40/8.0.29/8.3.8. It has been rated as critical. This issue affects some unknown functionality of the component Storage Engine Integration Layer. The manipulation with an unknown input leads to a input validation vulnerability. Using CWE to declare the problem leads to CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. Impacted is availability. The summary by CVE is:

A security issue in the MongoDB Server's storage engine integration layer allows an authenticated user with collection creation privileges to cause a persistent denial of service. Insufficient validation of user-supplied storage configuration options permits values that, once persisted to durable metadata, trigger a fatal assertion failure when the metadata is subsequently read by diagnostic operations. The corrupted metadata persists across server restarts and is replicated to other cluster members, requiring manual operator intervention to restore service.

The advisory is shared at jira.mongodb.org. The identification of this vulnerability is CVE-2026-82065 since 08/28/2026. The exploitation is known to be easy. The attack may be initiated remotely. Neither technical details nor an exploit are publicly available.

Upgrading to version 7.0.41, 8.0.30 or 8.3.9 eliminates this vulnerability.
