Overview

@theia/mini-browser is a Theia - Mini-Browser Extension

Affected versions of this package are vulnerable to Arbitrary Code Execution. In Eclipse Theia, the "mini-browser" extension allows a user to preview HTML files in an iframe inside the IDE. But with the way it is made it is possible for a previewed HTML file to trigger an RCE. This exploit only happens if a user previews a malicious file.
