Technical details
A Server-Side Request Forgery (SSRF) vulnerability exists in ThingsBoard versions prior to 4.2.1 within the dashboard's Image Upload Gallery feature. The vulnerability is rooted in the improper handling of SVG files; an attacker can upload a malicious SVG containing external references that the server-side parser attempts to resolve. This allows an unauthenticated or low-privileged attacker to initiate outbound network requests from the server's context. This can be leveraged to access internal metadata services, scan internal networks, or interact with other internal resources not exposed to the public internet. The issue was addressed in version 4.2.1 by implementing a Content-Security-Policy (CSP) header and improving image processing.
