Description
YesWiki before 4.7.0 contains a stored cross-site scripting vulnerability in handlers/page/referrers_sites.php that allows unauthenticated attackers to inject scripts via crafted Referer headers. Attackers can send a Referer hostname containing HTML metacharacters that renders unescaped, executing JavaScript for any referrer-sites page visitor to perform same-origin authenticated actions.
