Sonicverse は、ダッシュボード API クライアントにおけるユーザー制御の URL を介したサーバーサイドリクエストフォージェリ (SSRF) の脆弱性を抱えています

The SSRF vulnerability in Sonicverse allows an authenticated operator to make arbitrary HTTP requests on behalf of the Sonicverse server. This means an attacker could potentially scan internal networks for exposed services, access sensitive data stored behind firewalls, or even interact with internal APIs without proper authorization. For example, an attacker could attempt to access internal databases, configuration files, or other critical systems. The blast radius extends to any internal resources accessible via HTTP or HTTPS. This vulnerability is particularly concerning because it requires only authentication, making it relatively easy to exploit if an attacker gains access to a valid operator account.

Organizations using Sonicverse Radio Audio Streaming Stack, particularly those who deployed the stack using the provided install.sh script or the one-liner bash command, are at risk. Shared hosting environments where Sonicverse is installed are also at increased risk due to the potential for cross-tenant exploitation.

• nodejs: Monitor the Sonicverse API endpoint for unusual outbound HTTP requests. Use Node.js debugging tools to inspect the api.ts file for suspicious URL handling.

# Example: Check for outbound requests using curl
curl -v <sonicverse_api_endpoint>/some/api/path

• generic web: Examine access and error logs for requests to unusual or internal IP addresses originating from the Sonicverse server.

grep '127.0.0.1' /var/log/nginx/access.log

• linux / server: Use lsof or netstat to identify processes making outbound connections to unexpected destinations.

lsof -i | grep sonicverse

The primary mitigation for CVE-2026-40089 is to upgrade the Sonicverse Radio Audio Streaming Stack to version cb1ddbacafcb441549fe87d3eeabdb6a085325e4 or later. If an immediate upgrade is not possible, consider implementing temporary workarounds such as restricting outbound network access from the Sonicverse server using a firewall or proxy. Additionally, carefully review and restrict the permissions granted to operator accounts to minimize the potential impact of a compromised account. After the upgrade, confirm the fix by attempting to trigger the SSRF vulnerability with a known malicious URL; the request should be blocked or rejected.
