The issue arises from insufficient URL prefix validation in the 'validate_url_is_in_s3_bucket()' function and a permission callback that relies on a shared token accessible to users with the 'frm_view_forms' capability, without checking for 'install_plugins' or 'activate_plugins' privileges. The vulnerability is exploitable by authenticated users with subscriber-level access and above, provided the site is using the free version of the plugin (Formidable Pro is not installed).</p> highadvisorywordpressvulnerability
