HTTP Library Flaw Lets Attackers Crash Your Server with One Request

high

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.

Outdated Markdown Library Can Be Used to Slow Down or Crash Your App

medium

Your application uses a version of a popular text-formatting library (markdown-it) that contains a flaw in how it processes certain text patterns. If your app lets users submit markdown content — such as comments, notes, or documentation — someone could craft a specially formatted message that causes your server to work extremely hard processing it, potentially slowing down or making your app unavailable to other users. A fix is available and is a straightforward upgrade.

Outdated Date Library Can Be Used to Slow Down or Crash Your App

medium

Your application is using an old version of Moment.js, a popular tool for handling dates and times. This version has a known weakness: if someone sends it a very long, specially crafted piece of text, it can cause your app to freeze or become unresponsive while it tries to process it. Think of it like a lock that jams when you insert a bent key — the door stops working for everyone until the jam clears.

Outdated Date Library Can Be Used to Slow Down or Crash Your Application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Your application uses an outdated version of Moment.js — a popular tool developers use to handle dates and times.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.

Outdated Lodash Library Allows Attackers to Run Malicious Code on Your Server

high

Your application uses an old version of Lodash (3.10.1), a popular JavaScript helper library. This version has a known security flaw that could allow an attacker with access to your system to run their own commands on your server. Upgrading to the latest version closes this gap completely.

Outdated Lodash Library Allows Application Logic Tampering

high

Your application uses a very old version of Lodash (3.10.1), a popular JavaScript utility library, that has a known security flaw. An attacker who can send crafted data to your application could manipulate how JavaScript objects behave globally — think of it like someone secretly changing the rules of the game for every player at once. Upgrading to the latest version of Lodash closes this gap immediately.

Outdated JavaScript Utility Library Allows Application Disruption (CVE-2018-16487)

high

Your application is using a very old version of lodash (3.10.1), a popular JavaScript helper library, that contains a known security flaw. An attacker who can send crafted data to your application could use this flaw to disrupt your service or, in some cases, interfere with how your application behaves. The fix is a straightforward library upgrade.

Outdated JavaScript Utility Library Allows Application Behavior Tampering

medium

Your application uses an old version of a popular JavaScript helper library called Lodash (version 3.10.1) that contains a known security flaw. An attacker who can send crafted data to your app could manipulate how it processes objects internally, potentially disrupting its behavior. Upgrading to the latest version of Lodash takes a developer under an hour and fully resolves the issue.

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.

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

medium

Your application uses an old version of Moment.js, a popular JavaScript tool for handling dates and times. 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.

Axios Library Flaw Lets Attackers Crash Your Node.js Server

high

Your application uses a version of Axios — a very common networking library — that has a flaw allowing an attacker to send a specially crafted request that forces your server to consume all available memory and crash. This causes downtime for your users and can be triggered with a single request, requiring no login or special access.

Outdated HTTP Library Can Leak API Keys to Unintended Servers

high

Your application uses an outdated version of axios, a popular tool for making web requests. Due to a flaw in how it handles certain URLs, API keys or other credentials your app sends with requests could be accidentally forwarded to the wrong server — including servers controlled by an attacker. This affects both server-side and browser-based usage of the library.
