Outdated Date Library Can Be Used to Slow Down or Crash Your Application

high

Your application uses an outdated version of Moment.js — a popular tool developers use to handle dates and times. This version has a known flaw where sending it an unusually long piece of text can cause it to get stuck processing, slowing your app to a crawl or making it temporarily unavailable to users. This only matters if your app accepts date input directly from users or external sources.

This version has a known flaw that could allow an attacker who can send crafted input to your app to corrupt how your application handles data internally — potentially causing it to crash or behave in unexpected ways. Exploiting this requires specific conditions, but the fix is a straightforward library update.

This version has a known flaw where a specially crafted date string can cause the server to get stuck processing it, making your app slow or unresponsive for other users. Think of it like a trick question that causes a calculator to spin forever — it doesn't break the calculator, but it stops it from doing anything else.
