There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

  - A user with Editor permissions can place a malicious script in the attribution field of a Geomap panel's
    XYZ tile layer via a template variable. The script then executes in the browser of any user who views the
    affected dashboard (stored cross-site scripting). (CVE-2026-9029)

  - A user with Editor permissions can craft a dashboard whose table (TableNG) panel contains a malicious
    field name that executes as a script in the browser of any user who views the dashboard (stored cross-site
    scripting). (CVE-2026-8595)

  - An unauthenticated attacker can repeatedly call Grafana's OAuth login route with unique values, causing
    unbounded memory growth that can eventually exhaust memory and crash the Grafana instance (denial of
    service). (CVE-2026-8609)

  - A user with Viewer permissions can use specially crafted requests to the Tempo and Loki data source
    plugins to reach unintended backend endpoints. Depending on the backend configuration this can expose data
    source credentials, leak internal responses, or trigger administrative actions on the configured backend.

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21366-1 advisory.

    Changes in grafana:

    - CVE-2026-33382: Limit the size of the request body before processing it at several Grafana API endpoints     (bsc#1271331)
    - CVE-2026-8595: Fix stored XSS in the table panel (bsc#1271557)

The version of Grafana Labs installed on the remote host is affected by multiple vulnerabilities, including:

  - The public dashboard query endpoint does not limit request body size before processing, allowing     unauthenticated attackers to trigger excessive memory allocation by sending arbitrarily large JSON payloads.
    This can lead to denial of service through memory exhaustion. (CVE-2026-42127)

  - An unauthenticated attacker can repeatedly call Grafana's OAuth login route with unique values, causing     unbounded memory growth that can eventually exhaust memory and crash the Grafana instance (denial of     service). (CVE-2026-8609)

  - Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body     before processing it. An attacker can send very large payloads that force excessive memory allocation,     potentially exhausting memory and causing a denial of service. (CVE-2026-33382)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body     before processing it. An attacker can send very large payloads that force excessive memory allocation,     potentially exhausting memory and causing a denial of service. (CVE-2026-33382)

Note that Nessus relies on the presence of the package as reported by the vendor.
