CVE-2026-40882

Openremote XML external entity (XXE)

7.6 HIGHPublic exploitEPSS 0.36%
  1. Published22 Apr 2026

Description

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.
