Practical Security Guides For Your Team

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Your website uses an outdated version of React (a popular tool for building web pages) that has a known security flaw.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 Because the framework is no longer maintained, this particular vulnerability has no official patch — the real fix is to plan a migration to a modern framework.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 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Your website uses an outdated version of Bootstrap — a popular design toolkit used by millions of websites.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.

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.

Your 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.

Your website uses an old version of AngularJS (a JavaScript framework) that has a known security flaw. Because of this flaw, an attacker could bypass a built-in safety filter and display images or content from unauthorized sources on your pages — a technique known as content spoofing. The bigger concern here is that AngularJS itself is no longer maintained by its creators, meaning this flaw will never receive an official fix.

Your 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.
