CVE-2026-33950 — AI Deep Analysis Summary

🚨 **Essence**: Signal K Server has a critical security flaw allowing **unauthorized admin role injection**.…

🛡️ **Root Cause**: **CWE-285** (Improper Authorization). The system fails to validate the 'admin' role properly during injection, allowing bypass of access controls.

📦 **Affected**: **Signal K Server** (Product: signalk-server). Specifically versions **before 2.24.0-beta.4**. 🚫 Not fixed in older releases.

💀 **Attacker Capabilities**: Can escalate to **Admin privileges**. This leads to **High Confidentiality** and **High Integrity** impact, plus **Low Availability** risk. Full system compromise possible.

⚡ **Exploitation Threshold**: **LOW**. CVSS indicates **Network** accessible, **Low Complexity**, **No Privileges** required, **No User Interaction** needed. Easy to exploit remotely.

🔍 **Public Exploit**: **No**. The `pocs` field is empty. No public Proof-of-Concept or wild exploitation code is currently available.

🔎 **Self-Check**: Check your installed version of **Signal K Server**. If it is **< 2.24.0-beta.4**, you are vulnerable. Use package managers or version commands to verify.

✅ **Fixed**: **Yes**. Official patch released in **v2.24.0-beta.4**. See GitHub Advisory **GHSA-x8hc-fqv3-7gwf** for details.

🛑 **No Patch Workaround**: If you cannot upgrade immediately, restrict network access to the server. Implement strict **WAF rules** or **firewall policies** to block unauthorized role manipulation attempts.

🔥 **Urgency**: **HIGH**. CVSS Score implies severe impact (C:H, I:H). Since it requires no auth and is network-accessible, patch immediately to prevent unauthorized admin takeover.
