Practical Security Guides For Your Team

Your website uses an outdated version of a code-highlighting tool called Highlight.js (version 9.10.0).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.

Your application uses an outdated version of Axios, a popular tool for making web requests. A known flaw in this version means that a malicious server — or an unexpectedly large response — can keep sending data even after your app has told it to stop, eventually overwhelming your server and causing it to crash or become unresponsive. The fix is a straightforward library upgrade.

Your website uses an outdated version of a popular form-checking tool called jQuery Validation (version 1.14.0).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.

Your application uses a JavaScript helper library called Underscore.js that has a flaw in two of its functions. Under specific conditions, an attacker could send specially crafted deeply-nested data to your server, causing it to crash and become temporarily unavailable. Think of it like sending a letter with 4,500 envelopes nested inside each other — the library tries to open every one and runs out of room.

Your website uses Next.js, a popular web framework, which includes a feature that automatically resizes and optimises images for visitors. A flaw in versions before 16.1.7 means this feature stores an unlimited number of image variants on disk with no cap — like a filing cabinet with no limit on how many folders can be added. An attacker could deliberately flood this cache to fill up your server's storage and take your site offline.

Your 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.

Your application uses a popular networking library called Axios to make web requests. A flaw in this library means that if your app accepts data from users, parses it as JSON, and passes it into Axios, an attacker can send a single specially crafted request that instantly crashes your server. Think of it like a specific combination lock that, when entered, causes the door to fall off its hinges rather than just staying locked.

Your website is running an older version of Next.js (a popular web framework) that has a known weakness in how it handles images. An attacker could repeatedly trigger the image processing feature in a way that overloads your server, making your site slow or temporarily unavailable. Upgrading to the latest version closes this gap.

Your 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.

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.

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 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.
