Security releases 2.0.8 and 2.1.2
It was brought to our attention that identifier quoting in Doctrine DBAL has a potential security problem when user-input is passed into this function, making the security aspect of this functionality obsolete. We fixed as soon as we realized it and apologize for to our users for this error.
If you make use of AbstractPlatform::quoteIdentifier() or Doctrine::quoteIdentifier() please upgrade immediately. The ORM itself does not use identifier quoting in combination with user-input, however we still urge everyone to update to the latest version of DBAL.
