Summary

ThingsBoard vulnerable to stored cross-site scripting (XSS) vulnerability in the dashboard's Image Upload Gallery feature

Details

ThingsBoard versions < 4.2.1 contain a stored cross-site scripting (XSS) vulnerability in the dashboard's Image Upload Gallery feature. An attacker can upload an SVG file containing malicious JavaScript, which may be executed when the file is rendered in the UI. This issue results from insufficient sanitization and improper content-type validation of uploaded SVG files.

CVE-2025-34281 (GCVE-0-2025-34281)

Vulnerability from cvelistv5 – Published: 2025-10-17 18:33 – Updated: 2026-02-10 15:32

Title

Stored Cross-Site Scripting (XSS) in ThingsBoard

Summary

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 user's 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.

Severity
