Description
YesWiki before 4.6.7 contains a cross-site request forgery vulnerability in the ajaxdeletepage handler, which permanently deletes a page on any GET request carrying a jsonp_callback parameter without checking a CSRF token. Attackers can lure a logged-in administrator or page owner to a crafted link to delete arbitrary pages along with their ACLs, links, triples, comments and referrers.
