Automatically generated NumberFilter
instances, whose value was later converted to an integer, were subject to potential DoS from maliciously input using exponential format with sufficiently large exponents.
Version 2.4.0+ applies a MaxValueValidator
with a a default limit_value
of 1e50 to the form field used by NumberFilter
instances.
In addition, NumberFilter
implements the new get_max_validator()
which should return a configured validator instance to customise the limit, or else None
to disable the additional validation.
Users may manually apply an equivalent validator if they are not able to upgrade.
