  script_tag(name:"insight", value:"WordPress is prone to multiple vulnerabilities:

  - Authenticated users with upload permissions (like authors) are able to inject JavaScript into some media
    file attachment pages in a certain way. This can lead to script execution in the context of a higher
    privileged user when the file is viewed by them. (CVE-2020-4047)

  - Due to an issue in wp_validate_redirect() and URL sanitization, an arbitrary external link can be crafted
    leading to unintended/open redirect when clicked. (CVE-2020-4048)

  - When uploading themes, the name of the theme folder can be crafted in a way that could lead to JavaScript
    execution in /wp-admin on the themes page. This does require an admin to upload the theme, and is low
    severity self-XSS. (CVE-2020-4049)

  - Misuse of the 'set-screen-option' filter's return value allows arbitrary user meta fields to be saved. It
    does require an admin to install a plugin that would misuse the filter. Once installed, it can be leveraged
    by low privileged users. (CVE-2020-4050)

  - Comments from a post or page can sometimes be seen in the latest comments even if the post or page is not
    public. (CVE-2020-25286)");
