Practical Security Guides For Your Team

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.

Your website uses a popular 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 the version you're running means that filter has a gap: under specific conditions, a crafted piece of content can slip through and run malicious code in a visitor's browser. A patch is already available and the fix is a straightforward version upgrade.

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.

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.

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.

Your website uses an outdated version of React (a popular tool for building web pages) that has a known security flaw. If your site generates pages on the server and allows user input to influence how those pages are built, an attacker could inject malicious code that runs in your visitors' browsers. This only affects server-rendered React apps — if your site is purely client-side, you are not at risk.

Your website uses an old version of jQuery (a common JavaScript tool) that has a known security flaw. If your site processes any HTML content from users or external sources, that content could contain hidden instructions that run automatically — without any warning. Upgrading jQuery to a modern version closes this gap.

Your website uses AngularJS 1.x, an old JavaScript framework that was officially retired in early 2022 and will never receive security updates again. A known flaw in this version can allow malicious scripts to run in a visitor's browser under specific conditions. Because the framework is no longer maintained, this particular vulnerability has no official patch — the real fix is to plan a migration to a modern framework.

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.

Your website uses an outdated version of jQuery (3.3.1), a popular JavaScript library. 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.

Your server's SSH service — the secure tunnel used for remote administration — is configured with encryption options that have a known flaw. An attacker positioned between your server and a connecting administrator (for example, on the same network) could quietly weaken that tunnel during the initial handshake, potentially stripping away some security protections before either side notices. Think of it like a tampered lock that looks fine from the outside but is slightly easier to pick.

Your website uses an outdated version of Bootstrap — a popular design toolkit used by millions of websites. The version in use has a known flaw in its collapsible panel feature that could allow someone to inject malicious code into your pages if they can influence the content on your site. This is a medium-priority issue: it requires specific conditions to exploit, but it is a well-documented vulnerability with a straightforward fix.
