Overview

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') due to the lack of data extraction limits from compressed archives during board import. An attacker can consume excessive resources, potentially leading to a denial of service, by importing a board using a specially crafted zip (zip bomb).
