High risk79th percentile - higher than 79% of all known CVEs
Summary
An SSRF vulnerability in the Image Upload Gallery feature of ThingsBoard versions prior to 4.2.1 allows an attacker to upload a malicious SVG file referencing a remote URL. Server processing may trigger unintended outbound requests.
Risk Assessment
The risk involves potential access to internal services and resources within the organization's network, which could lead to data leakage or further compromise.
Recommendation
Immediately update ThingsBoard to version 4.2.1 or later, and consider restricting processing of external references in SVG files.
Other vulnerabilities in ThingsBoard
See all- CVE-2026-36537Critical
ThingsBoard v4.3.0.1 is vulnerable to an authentication bypass during the OAuth authorization code exchange. The application improperly trusts user-supplied identity data within the user parameter of the /login/oauth2/code/ endpoint.
- CVE-2026-53676High
ThingsBoard contains a prototype pollution vulnerability which may lead to arbitrary code execution within a sandboxed context by a user who can log in to the affected product with the tenant administrator privilege (TENANT_ADMIN).
- CVE-2026-9568Medium
In ThingsBoard up to version 4.3.1.1, a vulnerability in the getGatewayDockerComposeFile function of /api/v1/provision (YAML Handler component) allows code injection. Remote attack is possible but difficult.
- CVE-2025-34281Medium
ThingsBoard versions prior to v4.2.1 allow an authenticated user to upload malicious SVG images via the Image Gallery, leading to stored XSS. The exploit can be triggered when any user accesses the public API endpoint or embeds the image in an iframe during widget creation. The vulnerability resides in ImageController, which fails to restrict JavaScript execution.
- CVE-2022-45608High
An issue in ThingsBoard 3.4.1 allows low-privileged attackers (CUSTOMER_USER) to escalate privileges to administrator level (TENANT_ADMIN or SYS_ADMIN). The attack requires knowledge of the corresponding API parameter (authority: value).
Original NVD description (English source)
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.
