CVE-2025-34282
ThingsBoard < v4.2.1 SVG Image SSRF
Description
ThingsBoard versions < 4.2.1 contain a server-side request forgery (SSRF) vulnerability in the dashboard's Image Upload Gallery feature. An attacker can upload a malicious SVG file that references a remote URL. If the server processes the SVG file in a way that parses external references, it may initiate unintended outbound requests. This can be used to access internal services or resources.
