"The AlmaLinux 9.2 host has a package installed that is affected by multiple vulnerabilities as referenced in the TuxCare
ALMALINUX9.2:CLSA-2025:1757427057 advisory.

  - Grafana is an open-source platform for monitoring and observability. Starting with the 8.1 branch and
    prior to versions 8.5.16, 9.2.10, and 9.3.4, Grafana had a stored XSS vulnerability affecting the core
    plugin GeoMap. The stored XSS vulnerability was possible because SVG files weren't properly sanitized and
    allowed arbitrary JavaScript to be executed in the context of the currently authorized user of the Grafana
    instance. An attacker needs to have the Editor role in order to change a panel to include either an
    external URL to a SVG-file containing JavaScript, or use the `data:` scheme to load an inline SVG-file
    containing JavaScript. This means that vertical privilege escalation is possible, where a user with Editor
    role can change to a known password for a user having Admin role if the user with Admin role executes
    malicious JavaScript viewing a dashboard. Users may upgrade to version 8.5.16, 9.2.10, or 9.3.4 to receive
    a fix. (CVE-2022-23552)

  - It is possible for a user in a different organization from the owner of a snapshot to bypass authorization
    and delete a snapshot by issuing a DELETE request to /api/snapshots/<key> using its view key. This
    functionality is intended to only be available to individuals with the permission to write/edit to the
    snapshot in question, but due to a bug in the authorization logic, deletion requests issued by an
    unprivileged user in a different organization than the snapshot owner are treated as authorized. Grafana
    Labs would like to thank Ravid Mazon and Jay Chen of Palo Alto Research for discovering and disclosing
    this vulnerability. This issue affects Grafana: from 9.5.0 before 9.5.18, from 10.0.0 before 10.0.13, from
    10.1.0 before 10.1.9, from 10.2.0 before 10.2.6, from 10.3.0 before 10.3.5. (CVE-2024-1313)

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