"The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is,
therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0596 advisory.

    Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

    CVE-2025-1088:
    An access control vulnerability was discovered in Grafana OSS where an Organization administrator could
    permanently delete the Server administrator account. This vulnerability exists in the DELETE
    /api/org/users/ endpoint.

    The vulnerability can be exploited when:

    1. An Organization administrator exists

    2. The Server administrator is either:

     - Not part of any organization, or
     - Part of the same organization as the Organization administrator
    Impact:

    - Organization administrators can permanently delete Server administrator accounts

    - If the only Server administrator is deleted, the Grafana instance becomes unmanageable

    - No super-user permissions remain in the system

    - Affects all users, organizations, and teams managed in the instance

    The vulnerability is particularly serious as it can lead to a complete loss of administrative control over
    the Grafana instance.

    CVE-2024-10452:
    Grafana is an open-source platform for monitoring and observability. The Grafana Alerting DingDing
    integration was not properly protected and could be exposed to users with Viewer permission.
    Fixed in versions 10.4.19+security-01, 11.2.10+security-01, 11.3.7+security-01, 11.4.5+security-01,
    11.5.5+security-01, 11.6.2+security-01 and 12.0.1+security-01

    CVE-2025-3580:
    In Grafana, an excessively long dashboard title or panel name will cause Chromium browsers to become
    unresponsive due to Improper Input Validation vulnerability in Grafana.
    This issue affects Grafana: before 11.6.2 and is fixed in 11.6.2 and higher.

    CVE-2025-3415:
    Organization admins can delete pending invites created in an organization they are not part of.
