CVE-2026-27893 — AI Deep Analysis Summary

🚨 **Essence**: The NemotronVL/KimiK25 models in vLLM have a **hardcoded trust** vulnerability. 💥 **Consequence**: Attackers can bypass security mechanisms to achieve **Remote Code Execution (RCE)** and gain full control …

🛠️ **Root Cause**: The code contains **hardcoded trust** logic for specific remote models (NemotronVL/KimiK25). 📉 **Vulnerability Point**: Remote inputs are not strictly validated, allowing the trust chain to be maliciou…

🎯 **Affected Component**: vLLM project. 📦 **Involved Models**: NemotronVL and KimiK25. ⚠️ **Version**: Unpatched older versions (refer to GHSA-7972-pg2x-xr59).

👨‍💻 **Attacker Privileges**: Gain **highest privileges** (Root/Admin) on the server. 🔓 **Data Theft**: Can read all **sensitive data**, model weights, and user information.

📉 **Exploitation Threshold**: **Very Low** (AC:L). 🔑 **Authentication Requirement**: **No authentication required** (PR:N). 👀 **User Interaction**: Requires only **user interaction** (UI:R), such as triggering a specific…

🧪 **Ready-made Exploit**: Currently **no public PoC** (pocs are empty). 🌐 **In-the-Wild Exploitation**: Refer to GitHub Advisory; the risk is confirmed, and potential attacks should be guarded against.

🔍 **Self-Check Methods**: 1️⃣ Check if **NemotronVL/KimiK25** models are loaded. 2️⃣ Verify if the vLLM version is lower than the fixed commit. 3️⃣ Scan the code for **hardcoded trust** logic.

🛡️ **Official Fix**: **Fixed**. 📝 **Fix Method**: Commit `00bd08ed` and PR `#36192`. 🔗 **Reference**: GitHub Security Advisory (GHSA-7972-pg2x-xr59).

🚫 **Temporary Mitigation**: 1️⃣ **Disable** loading of NemotronVL/KimiK25 models. 2️⃣ Implement **network isolation** to restrict remote access. 3️⃣ Upgrade to a vLLM version containing the fix as soon as possible.

🔥 **Urgency**: **Critical**. ⏱️ **CVSS Score**: 9.8 (C:H/I:H/A:H). 💡 **Recommendation**: Upgrade immediately; **do not delay**!
