CVE-2026-40089 — AI Deep Analysis Summary

🚨 **Essence**: Sonicverse has a Server-Side Request Forgery (SSRF) flaw. 📉 **Consequences**: Authenticated operators can trigger arbitrary HTTP requests from the backend dashboard.…

🛡️ **Root Cause**: **CWE-918** (SSRF). The API client accepts **user-controlled URLs** with **insufficient validation**. It blindly trusts input, allowing attackers to redirect requests to unintended destinations.

🎯 **Affected**: **Sonicverse** (Open-source self-hosted real-time radio audio streaming solution). 🏢 **Vendor**: `sonicverse-eu`. 📦 **Product**: `audiostreaming-stack`.…

💣 **Attacker Actions**: As an **authenticated operator**, you can initiate **arbitrary HTTP requests** from the server.…

🔐 **Threshold**: **Medium**. Requires **Low Complexity** (AC:L) and **No User Interaction** (UI:N). ⚠️ **Constraint**: Must be **Privileged** (PR:L - Low privileges required).…

📜 **Public Exp?**: **No**. The `pocs` field is empty. 🌐 **Reference**: A GitHub Security Advisory (GHSA-8vvj-7f7r-7v48) exists, but no public Proof-of-Concept code is available yet.

🔍 **Self-Check**: Scan for **Sonicverse** instances. 🧪 **Test**: If you have operator access, try injecting malicious URLs into API endpoints that accept user-controlled inputs.…

🩹 **Official Fix**: **Yes**. A security advisory was published on **2026-04-09**. 📢 **Action**: Check the GitHub repository for `audiostreaming-stack` for the patched version or mitigation guidance.

🚧 **No Patch?**: **Mitigation**: Restrict API access to trusted operators only. 🚫 **Network**: Implement strict egress filtering on the server hosting Sonicverse to block outbound requests to internal networks.…

⚡ **Urgency**: **High**. CVSS Score indicates **High** Confidentiality and Integrity impact. 📅 **Date**: Published April 2026. 🛡️ **Advice**: Patch immediately if you are a self-hosted operator.…
