NewCVE-2026-10055 (opens in a new tab)How to fix?
Upgrade @theia/request to version 1.73.0 or higher.
Overview
@theia/request is a Theia Proxy-Aware Request Service
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the request-service process. An attacker can access sensitive internal resources by sending crafted URLs to the backend, which then performs server-side HTTP requests and returns the responses. This can expose internal administrative endpoints, cloud instance metadata services, and other resources not intended to be accessible from the client. This is only exploitable if the service connection is reachable by untrusted users, such as in multi-tenant or publicly accessible deployments.
