CVE-2026-26216 — AI Deep Analysis Summary

🚨 **Essence**: Crawl4AI < 0.8.0 suffers from **Code Injection**. 📉 **Consequences**: Attackers execute arbitrary Python code via the `/crawl` endpoint, leading to **full server compromise** and remote command execution.…

🛡️ **CWE-94**: Improper Control of Generation of Code ('Code Injection'). 🐛 **Flaw**: The Docker API accepts a `hooks` parameter containing Python code and executes it directly using `exec()`.…

👥 **Vendor**: UncleCode. 📦 **Product**: Crawl4AI (LLM-friendly web crawler). 📅 **Affected Versions**: All versions **prior to 0.8.0**. 🚫 **Fixed in**: 0.8.0.

🔓 **Privileges**: Unauthenticated Remote Code Execution (RCE). 🗑️ **Data**: Full control over the server. 🌐 Attackers can run **any system command**, access sensitive data, and pivot to other internal systems.…

📉 **Threshold**: VERY LOW. 🚫 **Auth**: None required (Unauthenticated). ⚙️ **Config**: Direct access to the Docker API `/crawl` endpoint. 🎯 **Complexity**: Low (CVSS: L). Just send a malicious payload.

📢 **Public Exp?**: Yes, detailed in the Vendor Advisory (GHSA-5882-5rx9-xgxp) and Third-Party Advisory. 🌍 **Wild Exploitation**: High risk due to low barrier to entry.…

🔍 **Self-Check**: Scan for Crawl4AI services exposing the `/crawl` endpoint. 🧪 **Test**: Send a request with a `hooks` parameter containing harmless Python code (e.g., `print('test')`).…

✅ **Fixed**: Yes. 🛠️ **Patch**: Upgrade to **Crawl4AI version 0.8.0** or later. 📖 **Reference**: See the GitHub Security Advisory for official mitigation steps. 🔄 Update immediately.

🚧 **Workaround**: If upgrading is impossible, **block external access** to the `/crawl` endpoint via firewall rules. 🛑 Disable the `hooks` functionality if configurable. 🚫 Restrict network access to trusted IPs only.…

🔥 **Urgency**: CRITICAL. 🚨 **Priority**: P1. 📉 **CVSS**: 9.8 (Critical). ⏳ **Action**: Patch immediately. Unauthenticated RCE is a top-tier threat. 🏃‍♂️ Do not delay.
