Description
YesWiki before 4.6.7 contains a server-side request forgery vulnerability that allows page editors to make the server fetch arbitrary URLs via the url parameter of the Bazar valeur action. Attackers can embed the action with a champ parameter in wiki markup to reach loopback or internal services and partially read responses rendered into the page.
