CVE-2026-36764Public exploitNetwork attack vector

Authenticated internal network scanning via unrestricted JDBC URL

Published Apr 30, 2026 · Updated Apr 30, 2026

SSRF in SpringBlade 4.8.0 and earlier allows remote authenticated users to scan internal services through the blade-report endpoint. The testConnection method passes a user-controlled JDBC URL, username, and password directly to DriverManager.getConnection without destination validation. A valid report-viewer session reaches the endpoint, and response errors reveal whether targeted internal hosts and ports accept connections.
