Practical Security Guides For Your Team
Clear, non-alarmist guidance for real web vulnerabilities so your team can prioritize fixes confidently.
Syntax Highlighter Library Can Be Used to Freeze or Crash Your App
mediumYour website uses an outdated version of a code-highlighting tool called Highlight.js (version 9.10.0). A known flaw in this version means that if your site lets users submit text that gets highlighted — like a code editor, comment box, or documentation tool — a malicious user could craft a special input that causes your server or browser to freeze up. This is only a concern if users can submit content that gets syntax-highlighted.
Outdated Form Validation Library Can Make Your Website Unresponsive
mediumYour website uses an outdated version of a popular form-checking tool called jQuery Validation (version 1.14.0). This version has a known flaw where a visitor could submit a specially crafted input — like a malformed URL — that causes your site to freeze while processing it. Think of it like a lock that jams if you insert a bent key: the door stops working for everyone until the jam clears.
Outdated HTTP Library Can Be Used to Knock Your App Offline
highYour application uses an old version of Axios (v0.12.0), a popular tool that helps your software communicate with other services over the internet. This version has a known flaw that lets anyone send a specially crafted request to slow your server to a crawl — potentially making your app unavailable to real users. Upgrading to a newer version takes a developer less than an hour and fully resolves the issue.
Outdated Form Validation Library Can Be Used to Slow Down or Crash Your Website
highYour website uses an outdated version of a popular form-checking tool called jQuery Validation (version 1.14.0). This version has a known flaw where a visitor can submit a specially crafted URL into a form field and cause your server to get stuck processing it, slowing down or making your site unavailable to other users. The fix is a straightforward library upgrade.
Outdated JavaScript Utility Library Can Be Used to Slow Down Your App
mediumYour 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Outdated Date Library Can Be Used to Slow Down or Crash Your App
mediumYour 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
highYour 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.
AngularJS Vulnerability Can Make Your Web App Freeze or Crash for Users
mediumYour website uses AngularJS, a web framework that reached its official end of life in December 2021 — meaning it no longer receives security fixes from its creators. A newly discovered flaw in AngularJS allows anyone to send a specially crafted piece of text to your app that causes it to freeze or become unresponsive, effectively locking out real users. Because AngularJS is no longer maintained, there is no official patch available.

Outdated JavaScript Framework Can Be Used to Take Your App Offline
highYour application uses AngularJS 1.8.3, an outdated JavaScript framework that contains a known security flaw (CVE-2024-21490). An attacker can send a specially crafted request that causes your app to freeze or crash — making it unavailable to your customers. Importantly, AngularJS reached its official end of life in December 2021 and will never receive a patch for this issue.
Outdated JavaScript Framework Can Be Used to Slow Down Your Web App
mediumYour web application uses an outdated version of AngularJS (a JavaScript framework) that contains a known flaw. A visitor could submit a specially crafted URL into a form field and cause your server or browser to freeze up while processing it, making your site slow or temporarily unresponsive for other users. This is a medium-severity issue — it doesn't expose data, but it can affect availability.
Outdated AngularJS Library Can Be Used to Slow Down Your Website
mediumYour website uses an outdated version of AngularJS (a JavaScript library) that contains a flaw in one of its built-in tools. An attacker could send a specially crafted request that causes your server or browser to get stuck doing unnecessary work, potentially slowing down or temporarily making your site unavailable to real users. Think of it like a prank caller who knows exactly what to say to put your receptionist on hold indefinitely.
