Very severe bug!
Please update to this version!
This bug may allow an attacker to post arbitrary data to your admin panel!
I’m myself quite worried about how big this hole was o_o
Files at the usual places:
Sourceforge for the whole package, and here for the patch (it will work from 0.702)
The comments locked bug (they weren’t locked, ahem :P) should be fixed as well.
PLEASE UPDATE!
