Description Martin Prpič 2015-01-07 05:35:36 EST

The Django project reports the following issue:

"""
Given a form that uses ``ModelMultipleChoiceField`` and ``show_hidden_initial=True`` (not a documented API), it was possible for a user to cause an unreasonable number of SQL queries by submitting duplicate values for the field's data. The validation logic in ``ModelMultipleChoiceField`` now deduplicates submitted values to address this issue.
"""

This issue is resolved in the upstream versions 1.7.3 and 1.6.10.

Acknowledgements:

Red Hat would like to thank the upstream Django project for reporting this issue.
