Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the IntlExtension process. An attacker can cause excessive memory consumption by supplying a large number of unique arguments to the format_datetime, format_date, format_time, format_number, or format_currency filters in templates, leading to unbounded allocation of ICU formatter objects that persist for the lifetime of the environment, especially in long-running runtimes.
