If it does then we need to make plans to address this exploit and also plan an upgrade.
Diagnoses
We are always updating the security on our versions of K2.
Resolution
it is possible that if the vulnerability exited in 4.6.7 it might also be available in prior versions of K2. We have been doing some improvements to the security in the new releases of K2, specially in 4.6.8 and 4.6.9. We are on 4.6.11 so I would strongly recommend to upgrade to at least 4.6.10.
