CVE-2026-6942 — AI Deep Analysis Summary

Q: What is this vulnerability? (Essence + Consequences)

🚨 **Essence**: Remote Command Injection in Radare2 MCP Server. 💥 **Consequences**: Attackers bypass filters using shell metacharacters to execute arbitrary OS commands. Total system compromise possible.

Q: Root Cause? (CWE/Flaw)

🛡️ **Root Cause**: **CWE-78** (OS Command Injection). 🔍 **Flaw**: Inadequate input validation. User-controlled input containing shell metacharacters is passed directly to the OS shell without proper sanitization.

Q: Who is affected? (Versions/Components)

📦 **Affected**: **Radare2 MCP Server**. 📅 **Versions**: **1.6.0 and earlier**. 🏢 **Vendor**: radareorg.

Q: What can hackers do? (Privileges/Data)

👑 **Privileges**: Full Remote Code Execution (RCE). 📊 **Impact**: High Confidentiality, Integrity, and Availability impact (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). Attackers gain full control over the host OS.

Q: Is exploitation threshold high? (Auth/Config)

⚡ **Threshold**: **LOW**. 🔓 **Auth**: None required (PR:N). 🌐 **Network**: Remote (AV:N). 👤 **User Interaction**: None (UI:N). Easy to exploit.

Q: Is there a public Exp? (PoC/Wild Exploitation)

📜 **Public Exp?**: **Yes/Implied**. 🔗 **Evidence**: GitHub Issue #45 contains technical description and exploit details. Patch commit exists, confirming exploitability.

Q: How to self-check? (Features/Scanning)

🔍 **Self-Check**: 1. Check installed version of Radare2 MCP Server. 2. Verify if version ≤ 1.6.0. 3. Scan for exposed MCP Server endpoints accepting unsanitized input.

Q: Is it fixed officially? (Patch/Mitigation)

✅ **Fixed?**: **Yes**. 🔧 **Patch**: Commit `482cde6500009112a8bc0b3fa8d2ef6180581ec0` addresses the issue. 📌 **Action**: Update to the latest version immediately.

Q: Is it urgent? (Priority Suggestion)

🔥 **Urgency**: **CRITICAL**. ⏳ **Priority**: **P1**. 🚀 **Reason**: Remote, unauthenticated, high-impact RCE. Immediate patching required to prevent total system takeover.
