CSS Files Node

Cascading Style Sheets (CSS) is a method of adding styles, such as fonts and colors, to a website.

CSS files can be internal or external. Internal CSS is hosted on your own website while external CSS is hosted somewhere else, not present on your website. In both cases, you insert a link to this file within the HTML code.

To protect the web application from possible attacks, it is important not to load and use untrusted CSS files. Additionally, if you load a CSS file over an HTTP connection, using clear text, it can be dangerous.

These files can act as an attack vector. Attackers can use CSS to add some malicious code into a webpage’s HTML and enable it to run within the content of a website. For instance, cybercriminals can extract data from a server by using CSS selectors.

Once the scan is completed, all CSS files are listed under the CSS Files node in the Knowledge Base, highlighted in red and bold. You can access the same information in the Knowledge Base Report and Knowledge Base Tab.



Acunetix 360 forms Knowledge Base Nodes on its findings. If the CSS Files node is not listed, it means that Acunetix 360 did not find any.

For further information, see Knowledge Base Nodes.
