Description

The Newsletter WordPress plugin before 7.4.5 does not sanitize and escape the $_SERVER['REQUEST_URI'] before echoing it back in admin pages. Although this uses addslashes, and most modern browsers automatically URLEncode requests, this is still vulnerable to Reflected XSS in older browsers such as Internet Explorer 9 or below.

Affected WordPress components

  • Newsletter – Send awesome emails from WordPress Plugin · newsletter
    Possible match Active
    From 7.4.5 (including) to 7.4.5 (excluding); Before 7.4.5
    View on WordPress.org
  • newsletter Theme · newsletter
    Possible match Homeless
    From 7.4.5 (including) to 7.4.5 (excluding); Before 7.4.5
    View on WordPress.org

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

  • Unknown Newsletter – Send awesome emails from WordPress — From 7.4.5 (including) to 7.4.5 (excluding)
