CVE-2026-86671: Eclipse Che SSRF in SCM and factory resolver endpoints

CVE-2026-86671 · Severity: info · Published 2026-10-05

Eclipse Che is a web-based development environment platform. An authenticated user can exploit an unvalidated URL fetcher to read local files (including Kubernetes credentials), access internal services and cloud metadata endpoints, and steal stored authentication tokens by pointing the system to attacker-controlled servers. Attackers can also trick users into opening malicious workspace configurations that exfiltrate credentials without the user taking direct action.

Technologies: Eclipse Che. Vendors: Eclipse.

Technical details

The `/api/scm/resolve` and `/api/factory/resolver` endpoints pass attacker-controlled URLs directly to URLFetcher without scheme or host validation, calling `new URL(url).openConnection()` and returning the response body. An authenticated attacker can exploit this Server-Side Request Forgery (SSRF) to access file://, internal HTTP services, and cloud metadata endpoints (169.254.169.254); SCM personal access tokens are automatically attached as Authorization headers to any destination. The vulnerability also affects users opening workspaces with malicious devfile parent.uri values, enabling credential theft without authentication.

Affected products

Eclipse Che 7.29.0 and later
