About Exsied

Aufum Team | 2024-08-05

Exsied: Extremely simple editor. The pronunciation is /ɪkˈsiːd/, the same as exceed.

Exied is an editor from Fivim. It is a rich text editor that supports multiple file types.

At Aufum, we have customized it to better fit Aufum’s functionality.

In addition to common standard HTML elements, the supported features now include:

  • abcjs: Render music notation as sheet music from ABC text.
  • Excalidraw: Sketch hand-drawn style diagrams and collaborate in real time.
  • Mermaid: Generate diagrams and flowcharts from plain text descriptions.
  • Mind Elixir: Create and edit interactive mind maps quickly.

For greater flexibility, the internal HTML source code of Exsied can be edited, but to ensure security, the use of Javascript code is prohibited, including but not limited to the following examples:

<div>Welcome <style>.XSS{background-image:url("javascript:alert('XSS')");}</style><a class=xss></a>User</div>


<img src=x onerror=alert(1)//>


<svg><g/onload=alert(2)//<p>


<a href="javascript:alert('XSS1')" onmouseover="alert('XSS2')">Click Here<a>


<p>Text<iframe//src=jAva&Tab;script:alert(3)>Content</p>


<math><mi//xlink:href="data:x,<script>alert(4)</script>">


<script type="text/javascript" src="https://a.com/b.js"></script>
