What is CVE-2025-34282?

ThingsBoard versions prior to 4.2.1 are susceptible to a server-side request forgery (SSRF) vulnerability within the Image Upload Gallery feature. This security issue arises when an attacker uploads a malicious SVG file that contains references to remote URLs. If the server processes these SVG files and parses the external references, it may trigger unintended outbound requests. Such requests can potentially expose internal services or sensitive resources, thereby posing significant security risks.
