info:
  name: PhastPress < 1.111 - Open Redirect
  author: 0x_Akoko
  description: |
    There is an open redirect in the PhastPress WordPress plugin before 1.111 that allows an attacker to malform a request to a page
    with the plugin and then redirect the victim to a malicious page. There is also a support comment from another user one year
    ago (https://wordpress.org/support/topic/phast-php-used-for-remote-fetch/) that says that the php involved in the request only
    go to whitelisted pages but it's possible to redirect the victim to any domain.
