Practical Security Guides For Your Team

Your web server is missing a simple one-line instruction that tells browsers how to handle the files it sends. Without it, some browsers may try to 'guess' what type of file they've received — and in certain situations, that guess could cause a harmless-looking file to be treated as executable code. Think of it like a label on a package: without it, the delivery driver has to guess what's inside.

Your website uses an outdated version of Bootstrap — a popular design toolkit — that has a known security flaw. A malicious actor who can influence tooltip or popover content on your site could use this flaw to run unwanted code in a visitor's browser. The fix is a straightforward library upgrade.

Your website uses an old version of Bootstrap (a popular design toolkit) that has a known security flaw. A specific button feature in this version doesn't properly filter out malicious code, meaning that if any user-supplied text ever reaches those buttons, it could run unwanted scripts in your visitors' browsers. Bootstrap 3 is also no longer maintained, so no official fix will be released for this version.

Your website uses an outdated version of Bootstrap (a popular design toolkit) that contains a known security flaw. An attacker who can influence the content on your pages could use this flaw to run malicious code in your visitors' browsers. The fix is straightforward: update Bootstrap to a newer version.

Your website uses an old version of Bootstrap (a popular design toolkit), which has a known weakness that could allow a malicious script to run in a visitor's browser under specific conditions. This requires an attacker to already be able to influence how your site's Bootstrap components are configured — it's not a direct, open door, but it is a gap worth closing. Upgrading Bootstrap to the patched version resolves it completely.

Your website is using an old version of Bootstrap (a popular design toolkit), which has a known security flaw in its tooltip feature. An attacker who can influence the content of a tooltip on your page could use it to run malicious code in your visitors' browsers. Upgrading Bootstrap to a patched version fully resolves this.

Your website is using an old version of Bootstrap (a popular design toolkit), which contains a known security flaw. The flaw could allow someone to inject malicious code into a tooltip element on your site — but only if they can also control the content of that tooltip. This is a medium-priority issue: worth fixing on your next development cycle, but not an emergency.

Your website uses an outdated version of jQuery (3.3.1), a common tool that helps web pages work smoothly. This version has a known flaw that could allow an attacker to sneak malicious code into your pages if your site processes any content from outside sources — like user-submitted text or third-party data. The fix is straightforward: update jQuery to the latest version.

Your website is using an old version of a very common JavaScript tool called jQuery (version 3.3.1). This version has a known flaw that can allow an attacker to sneak malicious code onto your web pages, which then runs in your visitors' browsers. The fix is straightforward: update jQuery to a newer version.

Your website uses an outdated version of a popular JavaScript table library called DataTables (version 1.10.19). This version has a known flaw that, under specific conditions, could allow malicious content to run in a visitor's browser. The fix is a straightforward library upgrade — no redesign or major work required.

Your website is missing a security instruction called a Content Security Policy (CSP). Think of it like a guest list for your website — it tells visitors' browsers which scripts and resources are allowed to run, and blocks everything else. Without it, your site is missing one layer of protection that could help limit the damage if another vulnerability were ever found.

Your website uses a 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 older versions of this library means the filter can be tricked under specific conditions, allowing malicious scripts to slip through. This only affects sites that have enabled a particular non-default setting called SAFE_FOR_TEMPLATES.
