Practical Security Guides For Your Team

Your website uses an outdated version of a popular form validation tool (jQuery Validation) that has a known security flaw. An attacker who can influence the text shown in form error messages could inject malicious code that runs in your visitors' browsers. This is a medium-severity issue — it requires a specific set of conditions to exploit, but the fix is straightforward.

Your website uses a popular library called DOMPurify to clean up user-submitted content before displaying it — think of it like a filter that removes dangerous code from text people type in. A flaw in older versions of this library means that, under specific conditions, that filter can be bypassed, allowing harmful scripts to slip through and run in your visitors' browsers. The fix is a straightforward library update.

Your website uses a popular library called DOMPurify to clean up user-submitted content before displaying it — think of it like a filter that removes dangerous code. A flaw in certain versions of this library means the filter has a few gaps: attackers who know about these gaps can sneak malicious scripts through, but only when the cleaned content is placed inside specific, less-common page sections. A patch is available and the fix is straightforward.

Your website uses a popular library called DOMPurify to clean up user-submitted content before displaying it — think of it like a spam filter for dangerous code. A flaw in certain versions of this library means that filter can be tricked, allowing a specially crafted piece of text to sneak harmful scripts past it. This only matters if your site places user-submitted content inside specific HTML form areas (like text boxes), but if it does, the risk is real.

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.

Your website uses an outdated version of a form validation library (jquery-validation) that has a known security flaw.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.

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 has a security header called a Content Security Policy (CSP) — think of it like a bouncer that controls which scripts are allowed to run on your pages. Right now, two settings in that policy ('unsafe-inline' and 'unsafe-eval') are telling the bouncer to let almost anyone in, which largely defeats the purpose of having one. This is a defence layer that isn't doing its job properly, not an active attack.

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 website uses an outdated version of jQuery, a common JavaScript tool. This version has a known flaw: if your site makes background data requests to other websites, a compromised or malicious third-party server could send back code that runs automatically in your visitors' browsers. Think of it like ordering a package and having the delivery driver hand you something unexpected that activates the moment you open the door.
