Outdated HTML Sanitizer Allows Script Injection in Specific Contexts

medium

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.

Outdated HTML Sanitizer Library Allows Malicious Scripts to Slip Through

high

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.

Outdated AngularJS Library Allows Fake Content to Be Shown to Your Users

medium

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 The bigger concern here is that AngularJS itself is no longer maintained by its creators, meaning this flaw will never receive an official fix.

Outdated HTML Sanitizer Can Be Bypassed to Inject Malicious Scripts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Outdated HTML Sanitizer Allows Malicious Scripts to Bypass Protection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.
