"The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the
RLSA-2022:5717 advisory.

  - Grafana is an open-source platform for monitoring and observability. In versions 5.3 until 9.0.3, 8.5.9,
    8.4.10, and 8.3.10, it is possible for a malicious user who has authorization to log into a Grafana
    instance via a configured OAuth IdP which provides a login name to take over the account of another user
    in that Grafana instance. This can occur when the malicious user is authorized to log in to Grafana via
    OAuth, the malicious user's external user id is not already associated with an account in Grafana, the
    malicious user's email address is not already associated with an account in Grafana, and the malicious
    user knows the Grafana username of the target user. If these conditions are met, the malicious user can
    set their username in the OAuth provider to that of the target user, then go through the OAuth flow to log
    in to Grafana. Due to the way that external and internal user accounts are linked together during login,
    if the conditions above are all met then the malicious user will be able to log in to the target user's
    Grafana account. Versions 9.0.3, 8.5.9, 8.4.10, and 8.3.10 contain a patch for this issue. As a
    workaround, concerned users can disable OAuth login to their Grafana instance, or ensure that all users
    authorized to log in via OAuth have a corresponding user account in Grafana linked to their email address.
    (CVE-2022-31107)
