Django 1.11.19 release notes

February 11, 2019

Django 1.11.19 fixes a security issue in 1.11.18.

CVE-2019-6975: Memory exhaustion in django.utils.numberformat.format()

If django.utils.numberformat.format() – used by contrib.admin as well as the floatformat, filesizeformat, and intcomma templates filters – received a Decimal with a large number of digits or a large exponent, it could lead to significant memory usage due to a call to '{:f}'.format().

To avoid this, decimals with more than 200 digits are now formatted using scientific notation.
