Outdated Bootstrap Library Contains Script Injection Weakness

medium

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.

Outdated Bootstrap Library Contains a Script Injection Flaw

medium

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.

Outdated Bootstrap Library Contains a Script Injection Flaw

medium

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.

Outdated jQuery Library Allows Malicious Scripts to Run in Users' Browsers

medium

Your website uses an outdated version of jQuery (3.3.1), a common tool that helps web pages work smoothly.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.

Missing Browser Security Policy Leaves Site Without a Content Filter

medium

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.

Outdated HTML Sanitizer Can Be Bypassed to Inject Malicious Scripts

medium

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.

Outdated HTML Sanitizer Allows Malicious Scripts to Bypass Protection

high

Your website uses a library called DOMPurify to clean up untrusted content before displaying it to users — think of it like a filter that strips out dangerous code. A flaw in the version you're running means that filter can be tricked into letting harmful scripts through. An attacker who can submit content to your site (e.g. via a form, comment box, or rich-text editor) could exploit this to run malicious code in your visitors' browsers.

Broken HTML Filter Lets Attackers Run Malicious Code in Users' Browsers

immediate

Your website uses a popular library called DOMPurify to clean up user-submitted content before displaying it — think of it like a bouncer checking IDs at the door. A flaw in older versions of this library means the bouncer can be tricked by a specific type of disguised content, allowing malicious code to slip through and run in your visitors' browsers. This is a confirmed, actively exploitable issue with public attack code available.

Text Editor Component Allows Malicious Scripts via Embedded Images

medium

Your website uses TinyMCE, a popular text editor that lets users write and format content. A security gap in versions before 7.0.0 means that if someone embeds a specially crafted image file (an SVG) using certain HTML elements, it could carry hidden malicious code. Think of it like a picture frame that secretly contains a hidden compartment — the image looks normal, but something harmful is tucked inside.
