Re: WordPress Search Function SQL-Injection



This looks like the bug described here: http://trac.wordpress.org/ticket/3722
"DB error when sanitized search string results in empty query" (Filed January 
31)

According to that page:

The same error results from searching for just a space.  In either case, adding 
other characters to the field results in the expected query.  It doesn't look 
like injection would be possible.
