CVE-2026-40882

OpenRemote is an open-source internet-of-things platform. Prior to version 1.22.0, the Velbus asset import path parses attacker-controlled XML without explicit XXE hardening. An authenticated user who can call the import endpoint may trigger XML external entity processing, which can lead to server-side file disclosure and SSRF. The target file must be less than 1023 characters. Version 1.22.0 fixes the issue.
