Outdated Vue.js Library Has a Known Security Flaw (CVE-2018-6341)

medium

Your website is using an old version of Vue.js (a JavaScript library that powers your web pages) that has a known security flaw. The flaw only affects sites that render pages on the server before sending them to visitors — a common setup for faster-loading or SEO-friendly sites. If your site works this way and passes user-supplied data into page attributes, the flaw could allow a malicious user to inject unwanted code into your pages. Upgrading Vue.js to a newer version fully resolves this.

Syntax Highlighter Library Can Be Used to Freeze or Crash Your App

medium

Your website uses an outdated version of a code-highlighting tool called Highlight.js (version 9.10.0).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

Outdated Form Validation Library Can Make Your Website Unresponsive

medium

Your website uses an outdated version of a popular form-checking tool called jQuery Validation (version 1.14.0).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

Outdated Form Validation Library Allows Script Injection in Error Messages

medium

Your website uses an outdated version of a form validation library (jquery-validation) that has a known security flaw. Under specific conditions, an attacker who can influence the text of form error messages could inject malicious code that runs in your visitors' browsers. This requires a fairly specific setup to exploit, but the fix is straightforward: update the library.

high

Your website uses an outdated version of a popular form-checking tool called jQuery Validation (version 1.14.0).

Outdated React Library Has a Script Injection Flaw (CVE-2018-6341)

medium

Your website uses an outdated version of React (a popular tool for building web pages) that has a known security flaw.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.

Outdated jQuery Library Allows Malicious Scripts to Run in Your Web App

medium

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.

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 jQuery Library Allows Malicious Tampering with Web Page Behaviour

medium

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.

Outdated Bootstrap Library Contains a Known Script Injection Flaw

medium

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.

Outdated Date Library Can Be Used to Slow Down or Crash Your Application

high

Your 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.

Outdated JavaScript Framework Can Be Used to Slow Down Your Web App

medium

Your 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.
