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Your website uses an outdated version of a popular form validation tool (jQuery Validation) that has a known security flaw.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 application uses a popular JavaScript utility library called Lodash. A security flaw in versions up to 4.17.x means that if any part of your app passes user-supplied data into a specific templating feature, an attacker could run their own code on your server. This is a bypass of a previous fix — the library patched one door but left another one open.

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 domain has a DMARC record, but it's set to 'monitor only' — meaning it watches for suspicious email activity but takes no action to stop it. Anyone can currently send emails that appear to come from your domain, and those emails will land in recipients' inboxes unchallenged. Think of it like having a security camera but no lock on the door.

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 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 server is configured to trust any website that contacts it, including malicious ones. This means if one of your logged-in users visits a harmful website, that site can silently pull data from your application — such as account details, API keys, or personal information — without the user knowing. Think of it like a bank teller who hands over account information to anyone who calls, as long as they say the right words.
