Name of the Vulnerable Software and Affected Versions Eclipse Theia versions 0.3.9 through 0.15.0

Description The issue concerns the "Mini-Browser" extension, published as "@theia/mini-browser" on npmjs.com, which is one of the default pre-packaged Theia extensions. This extension exposes an HTTP endpoint that allows reading the content of files on the host's filesystem, given their path, without restrictions on the requester's origin. This design is vulnerable to being exploited remotely through a DNS rebinding attack or a drive-by download of a carefully crafted exploit.

Recommendations For Eclipse Theia versions 0.3.9 through 0.15.0, consider disabling the "Mini-Browser" extension until a patch is available to prevent exploitation through the exposed HTTP endpoint. Restrict access to the HTTP endpoint exposed by the "Mini-Browser" extension to minimize the risk of exploitation.
