Practical Security Guides For Your Team
Clear, non-alarmist guidance for real web vulnerabilities so your team can prioritize fixes confidently.
Outdated jQuery Library Can Run Malicious Code in Visitors' Browsers
mediumYour 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.
Outdated Bootstrap Library Allows Script Injection via Tooltips
mediumYour website uses an outdated version of Bootstrap — a popular design toolkit — that has a known security flaw.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.
Outdated Bootstrap Library Allows Script Injection via Button Components
mediumYour 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 Bootstrap 3 is also no longer maintained, so no official fix will be released for this version.
Outdated Bootstrap Library Allows Malicious Script Injection
mediumYour website uses an outdated version of Bootstrap (a popular design toolkit) that contains a known security flaw.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.
Outdated Bootstrap Library Contains Script Injection Weakness
mediumYour 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Outdated Bootstrap Library Contains a Script Injection Flaw
mediumYour 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
mediumYour 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
mediumYour 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.
Outdated jQuery Library Allows Malicious Scripts to Run on Your Site
highYour 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.
Outdated DataTables Library Has a Known Script Injection Flaw
mediumYour 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.
Outdated DataTables Library Allows Tampering with Page Behaviour
highYour website uses an outdated version of DataTables — a popular JavaScript library for displaying sortable, searchable tables. The version in use has a known flaw that could allow an attacker to tamper with how the page behaves by injecting unexpected values into the library's internal logic. Think of it like a faulty lock that a previous repair didn't fully fix — a second patch is needed to close the gap.
Outdated HTML Sanitizer Can Be Bypassed to Inject Malicious Scripts
mediumYour 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.
