Description

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.
