Practical Security Guides For Your Team
Clear, non-alarmist guidance for real web vulnerabilities so your team can prioritize fixes confidently.
Outdated Markdown Library Can Be Used to Slow Down or Crash Your App
mediumYour 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 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Outdated Date Library Can Be Used to Slow Down or Crash Your App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Outdated Date Library Can Be Used to Slow Down or Crash Your Application
highYour application uses an outdated version of Moment.js — a popular tool developers use to handle dates and times.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.
Outdated AngularJS Library Can Be Used to Slow Down Your App
mediumYour website uses an old version of AngularJS (a JavaScript framework) that contains a flaw in how it processes certain web addresses. An attacker could send a specially crafted request that causes your server to spend a disproportionate amount of time processing it, potentially slowing down or temporarily making your app unresponsive for other users. This is a medium-severity issue — it's worth fixing, but it's not an emergency.
Outdated Date Library Can Be Used to Slow Down or Freeze Your Application
mediumYour 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.
Outdated HTML Sanitizer Can Be Bypassed to Inject Malicious Scripts
mediumYour website uses a library called DOMPurify to clean up user-submitted content before displaying it — think of it like a filter that strips out dangerous code. A flaw in older versions of this library means the filter can be tricked under specific conditions, allowing malicious scripts to slip through. This only affects sites that have enabled a particular non-default setting called SAFE_FOR_TEMPLATES.
