Description
WWBN AVideo contains an unauthenticated reflected cross-site scripting vulnerability in the url2Embed.json.php endpoint that allows attackers to inject malicious scripts by supplying URLs with HTML metacharacters. Attackers can mint an encrypted evideo payload containing unescaped markup, then deliver it as a legitimate-looking link on the site's own domain to execute JavaScript in victims' sessions and steal cookies or CSRF tokens.
