"The remote Redhat Enterprise Linux 8 host has a package installed that is affected by a vulnerability as referenced in
the RHSA-2023:3446 advisory.

    Flask is called a micro-framework because the idea to keep the core
    simple but extensible. There is no database abstraction layer, no form
    validation or anything else where different libraries already exist that
    can handle that. However Flask knows the concept of extensions that can add
    this functionality into your application as if it was implemented in Flask
    itself. There are currently extensions for object relational mappers, form
    validation, upload handling, various open authentication technologies and
    more.

    Security Fix(es):

    * Possible disclosure of permanent session cookie due to missing Vary:
    Cookie header (CVE-2023-30861)
