Description Mark Pellegrini 2006-03-06 23:40:18 UTC 
It is trivially easy to circumvent the spam blacklist by using an HTML comment
in the URL. 

Example: 
http://en.wikipedia.org/w/index.php?title=Wikipedia/Stable&diff=42542934&oldid=38860953
(Kapitalism.net is on the spam blacklist).

Comment 2 Brion Vibber 2006-03-09 21:16:06 UTC 
De-duping this. These extensions don't share code and work differently, 
so have to both be fixed separately.
Comment 3 Rob Church 2006-04-12 05:01:33 UTC 
Fixed in trunk, r13601.
Comment 4 Mark Pellegrini 2006-04-26 23:27:26 UTC 
Example:
http://en.wikipedia.org/w/index.php?title=Talk:Wikitruth&diff=50327924&oldid=50318100

http:///www.foo.org (notice the three slashes) is also an effective work around.
Comment 5 Rob Church 2006-04-28 23:18:59 UTC 
Second exploit should now be fixed in trunk, r13912.
