There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - A flaw was found in Keycloaks OpenID Connect user authentication, which may incorrectly authenticate
    requests. An authenticated attacker who could obtain information from a user request within the same realm
    could use that data to impersonate the victim and generate new session tokens. This issue could impact
    confidentiality, integrity, and availability. (CVE-2023-0264)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:1044 advisory.
