The MongoDB Go Driver's client-level bulk write operation may accept a caller-supplied database name containing a reserved separator character without escaping it before the name is used to build the target namespace for the operation. An application that passes untrusted input as a database name could therefore have the write directed at a database and collection other than the ones it intended. Only the Client.BulkWrite API is affected.

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:22032-1 advisory.

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:68334 advisory.

    Red Hat Edge Manager (RHEM) provides simple, scalable, and security-focused     management of edge devices and applications. It supports image-mode RHEL and     container workloads that run on Podman/Docker or Kubernetes.

    RHEM is now available as a standalone feature, providing greater flexibility for     edge deployments. In addition to the standalone version, RHEM continues to be     offered as a plugin for the following platforms:

    Red Hat Advanced Cluster Management (RHACM): Extends fleet management to edge     devices.
    Red Hat Ansible Automation Platform (AAP): Integrates edge management with     Ansible automation.

    This integration enables organizations to optimize the management and     orchestration of their fleets of edge devices; whether its thousands of     dispersed retail point-of-sale systems or industrial machinery on remote factory     floors.

    Value for customers and partners:

    * This solution not only helps customers manage thousands of devices but helps     scale operations.
    * To manage large-scale deployments, customers need to be able to integrate with     their existing management systems, support remote configuration and over-the-air     updates, and collect telemetry data for advanced analytics.
    * Red Hat Edge Manager offers a simple and security-focused lifecycle     management, from onboarding to decommissioning of edge devices.

    This complete end-to-end solution empowers organizations to gain the most value     from the fleets of devices that generate data, all from a centralized location.
