In Eclipse Theia since version 1.26.0, the backend \/services\/request-service RPC accepts an attacker-controlled URL from any client connected to the standard \/services messaging endpoint, performs the HTTP request server-side, and returns the full response body to the caller.<\/p>\n
Because the destination URL is neither validated nor allowlisted, a remote attacker with access to the Theia service connection can issue server-side HTTP requests to localhost or other backend-reachable hosts and read their responses, exposing internal administrative endpoints, cloud instance metadata services, and other resources that are intentionally outside the browser network boundary.<\/p>\n
The vulnerability affects deployments where the Theia service connection is reachable by untrusted users (for example, multi-tenant or publicly-reachable Theia deployments).<\/p>\n","protected":false},"excerpt":{"rendered":"
