I’m looking for a plugin or a setting which can add a warning page before redirecting to an external link in any topic, of-course on a self hosted discourse instance. The intention is to prevent phishing attacks.

You can rewrite external links using a theme-component as described by Redirect Page for External URLs - #14 by Johani

Advertencia antes de enlace externo
