CVE-2025-34281

Description

ThingsBoard in versions prior to v4.2.1 allows an authenticated user to upload malicious SVG images via the Image Gallery, leading to a Stored Cross-Site Scripting (XSS) vulnerability. The exploit can be triggered when any user accesses the public API endpoint of the malicious SVG images, or if the malicious images are embedded in an iframe element, during a widget creation, deployed to any page of the platform (e.g., dashboards), and accessed during normal operations. The vulnerability resides in the ImageController, which fails to restrict the execution of JavaScript code when an image is loaded by the users browser. This vulnerability can lead to the execution of malicious code in the context of other users sessions, potentially compromising their accounts and allowing unauthorized actions.
