In Eclipse Theia versions 0.3.9 through 0.15.0, one of the default pre-packaged Theia extensions is β€œMini-Browser”, published as β€œ@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.
