MegaMan has reported a vulnerability in vBSEO, which can be exploited by malicious people to conduct cross-site scripting attacks.
Input passed to the "u" parameter in member.php is not properly sanitised before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.
Successful exploitation requires that "Visitor Messages" feature is enabled.
Solution: No official solution is currently available.
