Q1What is this vulnerability? (Essence + Consequences)
🚨 **Essence**: Eclipse Che's `che-machine-exec` has an **Access Control Error**. 📉 **Consequences**: Remote attackers can execute arbitrary commands and steal secrets via JSON-RPC/websocket APIs.…
🛡️ **Root Cause**: **CWE-306** (Missing Authentication for Critical Function). The flaw lies in insufficient access control checks within the execution component, allowing unauthorized API interactions.
Q3Who is affected? (Versions/Components)
🏢 **Affected**: **Red Hat OpenShift Dev Spaces (RHOSDS) 3.22**. 📦 **Component**: Eclipse Che (specifically `che-machine-exec`). ☕ **Tech**: Java-based online IDE.
Q4What can hackers do? (Privileges/Data)
💻 **Actions**: Hackers can run **arbitrary commands** on the server. 🔑 **Data**: They can **steal secrets** (credentials, tokens). 🌐 **Scope**: Remote execution capabilities are granted to unauthorized users.
Q5Is exploitation threshold high? (Auth/Config)
⚠️ **Threshold**: **Medium**. 📝 **Auth**: Requires **PR:L** (Low privileges) - not fully anonymous, but easy to bypass. 🖱️ **UI**: Requires **UI:R** (User Interaction) - victim might need to trigger the API call.…
🚫 **Public Exp?**: **No**. The `pocs` array is empty in the data. 🕵️ **Status**: No public Proof-of-Concept or wild exploitation observed yet. Stay alert for new releases.
Q7How to self-check? (Features/Scanning)
🔍 **Check**: Scan for **Eclipse Che** instances. 📡 **API**: Monitor for unauthorized **JSON-RPC/websocket** traffic to `che-machine-exec`. 🛠️ **Tool**: Use vulnerability scanners targeting RHOSDS 3.22 components.
Q8Is it fixed officially? (Patch/Mitigation)
✅ **Fixed?**: **Yes**. 📜 **Advisories**: Red Hat issued **RHSA-2025:22620**, **RHSA-2025:22652**, and **RHSA-2025:22623**. 🔄 **Action**: Apply the official vendor patches immediately.
Q9What if no patch? (Workaround)
🚧 **No Patch?**: Isolate the `che-machine-exec` service. 🚫 **Network**: Restrict access to JSON-RPC/websocket APIs. 👮 **Monitor**: Enable strict logging for command execution attempts.…
🔥 **Urgency**: **HIGH**. 📅 **Date**: Published Jan 2026. 📈 **CVSS**: High severity (C:H, I:H, A:H). 🚀 **Priority**: Patch immediately to prevent RCE and secret theft. Do not ignore!
