In Eclipse Theia versions 0.3.9 through 0.15.0, one of the default pre-packaged Theia extensions is Mini-Browser, published as @theia/mini-browser on npmjs.com. This extension, for its own needs, exposes a HTTP endpoint that allows to read the content of files on the hosts filesystem, given their path, without restrictions on the requesters origin. This design is vulnerable to being exploited remotely through a DNS rebinding attack or a drive-by download of a carefully crafted exploit.
The product does not sufficiently verify the origin or authenticity of data, in a way that causes it to accept invalid data.
