EPSS: 0.5% probability of exploitation in the next 30 days
Public exploit or detection template: none known
Published: 2020-12-14 · updated 2026-06-17
Weakness: CWE-352

Description

A flaw was found in Eclipse Che in versions prior to 7.14.0 that impacts CodeReady Workspaces. When configured with cookies authentication, Theia IDE doesn't properly set the SameSite value, allowing a Cross-Site Request Forgery (CSRF) and consequently allowing a cross-site WebSocket hijack on Theia IDE. This flaw allows an attacker to gain full access to the victim's workspace through the /services endpoint. To perform a successful attack, the attacker conducts a Man-in-the-middle attack (MITM) and tricks the victim into executing a request via an untrusted link, which performs the CSRF and the Socket hijack. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Affected products

The Eclipse Foundation Eclipse Che: before 7.14.0 — fixed in 7.14.0

How to fix

Upgrade to a fixed version: The Eclipse Foundation Eclipse Che 7.14.0. Check the vendor advisory for mitigations.
