CRITICAL 9.1REMOTEUPGRADE
CVE-2025-34282 is a critical-severity flaw (CVSS 9.1) affecting thingsboard. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
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.
Why this priority
- Critical severity
- Public exploit reference
- Remotely exploitable, no login, no user action
A fixed release or distro patch exists.
