Detailsinfo

A vulnerability was found in Eclipse Che up to 7.121.0. It has been declared as problematic. Affected by this vulnerability is some unknown processing of the file /dashboard/api/data/resolver of the component Dashboard Backend. The manipulation with an unknown input leads to a server-side request forgery vulnerability. The CWE definition for the vulnerability is CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. As an impact it is known to affect confidentiality. The summary by CVE is:

In Eclipse Che versions 7.79.0 through 7.121.0, the dashboard backend's POST /dashboard/api/data/resolver endpoint passes a caller-supplied URL directly to an outbound HTTP GET request with no host filtering. An authenticated user can exploit this server-side request forgery (SSRF) to read responses from internal network addresses, including the cloud instance metadata service (169.254.169.254), loopback interfaces, RFC-1918 private ranges, and in-cluster Kubernetes services. The operator-configured allowlist (spec.devEnvironments.allowedSources.urls) is not consulted. The vulnerability is fixed in version 7.122.0, which adds private-address blocking, IPv4-mapped IPv6 bypass prevention, operator allowlist enforcement, and disables HTTP redirects on the outbound request.

The advisory is shared at gitlab.eclipse.org. This vulnerability is known as CVE-2026-86590 since 09/08/2026. The exploitation appears to be easy. The attack can be launched remotely. Technical details are known, but no exploit is available.

Upgrading to version 7.122.0 eliminates this vulnerability.
