YesWiki before 4.6.7 contains an unauthenticated server-side request forgery vulnerability that allows remote attackers to make the server fetch arbitrary hosts and ports via the {{valeur}} action's url parameter. Attackers can submit the action through the content parameter of handlers/page/render.php to probe internal HTTP services and read back response content matching fiche markup.
