Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: n8n (v1.0.0 to <2.0.0) suffers from a **Sandbox Escape** in the Python Code Node.β¦
π‘οΈ **Root Cause**: **CWE-693** (Protection Mechanism Failure). The Python execution environment lacks robust isolation, allowing code to break out of the intended sandbox boundary. π§±
Q3Who is affected? (Versions/Components)
π₯ **Affected**: Users running **n8n** versions **1.0.0** up to (but not including) **2.0.0**. π¦ Specifically impacts the **Python Code Node** component.
Q4What can hackers do? (Privileges/Data)
π **Impact**: Full **Remote Code Execution (RCE)**. Hackers gain the ability to run any command, potentially leading to total server compromise, data theft, or lateral movement. π΅οΈββοΈ
Q5Is exploitation threshold high? (Auth/Config)
π **Threshold**: **Low**. CVSS indicates **Network** access, **Low** complexity, and **No** user interaction required. β οΈ However, it requires **Low Privileges** (PR:L) to trigger initially.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Exploitation**: **Yes**, PoCs are public.β¦
π **Check**: Scan for n8n instances running Python Code Nodes. Verify version is **< 2.0.0**. Use the provided PoC scripts to test sandbox isolation integrity. π§ͺ
Q8Is it fixed officially? (Patch/Mitigation)
β **Fix**: Official advisory released via **GitHub Security Advisories** (GHSA-62r4-hw23-cc8v). π οΈ Upgrade to **n8n v2.0.0 or later** to patch the sandbox escape flaw.
Q9What if no patch? (Workaround)
π§ **Workaround**: If upgrading isn't immediate, **disable the Python Code Node** entirely. Restrict access to n8n interfaces and monitor logs for suspicious command execution attempts. π«
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. CVSS Score implies Critical impact (C:H, I:H). With public PoCs available, immediate patching to v2.0.0+ is strongly recommended. β³
