CVE-2026-7211 — AI Deep Analysis Summary

🚨 **Essence**: `GitSearchRequest` in `mcp_server.py` does not filter the `repo_url`/`pattern` parameters. 💥 **Consequence**: Can trigger **command injection** → Remote Code Execution (RCE).

🔍 **Root Cause**: Input is not securely processed. 📌 **Defect Point**: Suspected **CWE-77** (Command Injection). ⚙️ User input is directly concatenated when constructing system commands.

🎯 **Affected Versions**: dvladimirov MCP ≤ **0.1.0**. 🧩 **Affected Component**: **Git Search API** (`GitSearchRequest` in `mcp_server.py`).

👾 **What Hackers Can Do**: - 🛠️ Remotely execute arbitrary system commands. - 🗂️ Read/modify sensitive files. - 🕵️ Probe or control the server. - ❗ No local privileges required.

🟢 **Low Exploitation Threshold**: - 🔓 **No authentication required** (PR:N / UI:N). - 🌐 Triggerable if network reachable. - ⚙️ Exploitable with default configuration.

🚨 **Existing Exploit Available**: - ✅ Exploit code is publicly available. - 🧪 Although PoC is not listed in the data, it is marked as **exploitable**. - ⚠️ Risk of **in-the-wild exploitation** exists.

🔍 **Self-Check Method**: - 🔎 Check if using **MCP ≤ 0.1.0**. - 📂 Verify if `mcp_server.py` contains `GitSearchRequest`. - 🧪 Search if `repo_url`/`pattern` are directly concatenated into commands. - 📡 Use network scanning…

🛑 **Official Fix Status**: - ❌ **No patch available**. - 📬 The project team is aware (GitHub Issue #2), but has **not responded**. - 🚫 No mitigation measures have been released yet.

🛡️ **Temporary Mitigation Measures**: - 🔒 Restrict network access to the `GitSearchRequest` API (firewall/IP whitelist). - 🚫 Disable or remove the Git Search functionality. - 🧼 If you control the code, **filter/escape** …

🔥 **High Priority**: - 📈 CVSS 3.1: **6.3** (Medium severity, but easily exploitable). - 🌍 Remotely exploitable and requires no authentication → **Easily exploitable on a large scale**. - ⏰ **Immediate action recommended*…
