CVE-2026-26954 — AI Deep Analysis Summary

🚨 **Essence**: SandboxJS < 0.8.34 has a **Code Injection** flaw.…

🛡️ **Root Cause**: **CWE-94** (Code Injection). The software allows input that results in an array containing `Function` objects. This bypasses security controls and enables arbitrary code execution. ⚠️

🎯 **Affected**: **SandboxJS** by developer **nyariv**. 📦 **Version**: All versions **prior to 0.8.34**. If you are running 0.8.33 or lower, you are vulnerable!

💀 **Attacker Capabilities**: With **No Privileges** required, hackers can execute arbitrary code. They gain **High** access to sensitive data, can modify system integrity, and cause complete service disruption. 🌪️

🔓 **Exploitation Threshold**: **LOW**. CVSS indicates **Network** accessible, **Low** complexity, and **No** authentication/UI interaction needed. It is a remote, unauthenticated attack vector. 🎯

📜 **Public Exploit**: **No** public PoC or wild exploitation detected yet (POCs list is empty). However, the vulnerability is confirmed via GitHub Advisory. 🕵️‍♂️

🔍 **Self-Check**: Check your installed version of SandboxJS. If version < **0.8.34**, you are at risk. Look for configurations allowing `Function` arrays in input data. 🧪

✅ **Official Fix**: **Yes**. The vendor (nyariv) has issued a security advisory. Upgrade to version **0.8.34** or later to patch the code injection flaw. 🔄

🛑 **No Patch Workaround**: If you cannot upgrade immediately, **strictly sanitize inputs**. Ensure no `Function` objects or code-like strings are processed in arrays. Disable unnecessary network exposure. 🧱

🔥 **Urgency**: **HIGH**. CVSS Score is **Critical** (implied by H/H/H metrics). Remote code execution without auth is a top-priority fix. Patch immediately! 🚑
