Outdated HTML Sanitizer Allows Script Injection in Specific Contexts

high

Your application uses a library called DOMPurify to clean up untrusted content (like user-submitted text) before displaying it on your website. A flaw in the version you're running means that cleaning process can be bypassed under specific conditions, potentially allowing malicious scripts to run in a visitor's browser. Upgrading to the latest version closes the gap.

Outdated Markdown Library Can Be Used to Slow Down or Crash Your App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Outdated Lodash Library Could Allow Attackers to Disrupt Your Application

medium

Your application uses an outdated version of Lodash, a very common JavaScript helper library. This version has a flaw that could allow someone to corrupt core JavaScript functionality in your app, potentially causing it to crash or behave unexpectedly. A fix is available and is a straightforward upgrade.

Outdated JavaScript Utility Library Can Be Used to Slow Down Your App

medium

Your application uses an outdated version of a popular JavaScript helper library called Lodash. This version has a known weakness where a malicious user can send specially crafted text input that causes the server to get stuck processing it — like a tongue-twister that freezes a voice assistant. The fix is a straightforward library update.

Outdated Date Library Can Be Used to Slow Down or Crash Your App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Outdated Lodash Library Allows Application Tampering or Crash

high

Your application uses an outdated version of Lodash, a very common JavaScript helper library. 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.

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 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 May Leak Proxy Credentials During Web Requests

medium

Your application uses a JavaScript library called Axios to make web requests. A flaw in one of its supporting components means that if your app routes traffic through an authenticated proxy server, those proxy login credentials could be accidentally sent to the wrong destination when a redirect occurs. This only affects you if your app uses proxy authentication — if it doesn't, you're not at risk.

Outdated Axios Library Leaks Security Tokens to Third-Party Servers

medium

Your application uses an outdated version of Axios, a popular tool that helps your app communicate with other services over the internet. Due to a bug in this version, a special security token — designed to protect your users from a type of attack where a malicious website tricks their browser into taking actions on your site — is accidentally sent to any external server your app talks to, not just your own. Think of it like a master key being slipped under every door in the building instead of just your own front door.
