  - Due to the lack of handling user-submitted YAML placeholder expressions in the site configuration backend
    module, attackers could expose sensitive internal information, such as system configuration or HTTP
    request messages of other website visitors. A valid backend user account having administrator privileges
    is needed to exploit this vulnerability. (CVE-2022-23504)
