CVE-2026-22688 — AI Deep Analysis Summary

🚨 **Essence**: WeKnora (Tencent's LLM framework) suffers from **Command Injection**. <br>💥 **Consequences**: Attackers can execute arbitrary OS commands via flawed input validation on `stdio_config.command/args`.…

🛡️ **Root Cause**: **CWE-77** (Command Injection). <br>🔍 **Flaw**: Insufficient input validation/sanitization on configuration parameters (`stdio_config.command/args`).…

📦 **Affected**: **Tencent WeKnora**. <br>📉 **Versions**: All versions **prior to 0.2.5**. <br>🔧 **Component**: Core framework handling LLM/RAG document understanding.

💀 **Attacker Capabilities**: <br>✅ **Privileges**: Execute commands with the **same privileges** as the WeKnora process. <br>📂 **Data**: Read/Write/Modify any file accessible to the process.…

⚠️ **Exploitation Threshold**: <br>🔑 **Auth**: **PR:L** (Low). Requires **Low Privileges** (authenticated user). <br>🎯 **Access**: **AV:N** (Network). Remotely exploitable. <br>👁️ **UI**: **UI:N** (None).…

🚫 **Public Exploit**: **No**. <br>📄 **PoCs**: The `pocs` field is empty. <br>🔒 **Status**: No known wild exploitation reported yet. However, the CVSS score suggests high impact if exploited.

🔍 **Self-Check**: <br>1️⃣ Check WeKnora version: Is it `< 0.2.5`? <br>2️⃣ Audit `stdio_config` inputs: Look for unsanitized command/args in configuration files or API calls.…

✅ **Fixed**: **Yes**. <br>🔧 **Patch**: Upgrade to **WeKnora 0.2.5** or later.…

🛡️ **No Patch Workaround**: <br>1️⃣ **Input Validation**: Strictly whitelist/sanitize `stdio_config.command/args`. <br>2️⃣ **Least Privilege**: Run WeKnora with minimal OS permissions.…

🔥 **Urgency**: **HIGH**. <br>📊 **CVSS**: **9.8** (Critical). <br>🚀 **Action**: **Immediate Patching** required.…
