HTTP Library Flaw Lets Attackers Crash Your Server with One Request

Your application uses a popular tool called Axios to make web requests behind the scenes. A flaw in this tool means that if your app accepts any user-supplied data and passes it — even indirectly — into Axios, an attacker can send a single specially crafted message that instantly crashes your server. No password or account needed.

This version has a known flaw that could allow an attacker to tamper with how your web pages behave — but only if they can first get crafted data into a specific part of your site. Think of it like a faulty lock on an internal door: it's worth replacing, but someone still needs to get through the front door first.

Outdated Date Library Allows Attackers to Tamper with Server Files

high

Your application uses an outdated version of Moment.js — a popular tool for handling dates and times — that contains a known security flaw. If any part of your app lets users choose a language or locale (e.g., 'English', 'French'), an attacker could craft a malicious input to access or manipulate files on your server that they shouldn't be able to touch. This only affects server-side usage, not purely browser-based code.
