CVE-2026-40882 Details
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.
A vulnerability allowing XML External Entity (XXE) processing has been identified in OpenRemote versions through 1.21.0, specifically within the Velbus asset import feature. This issue arises because the import path parses user-controlled XML without adequate protections against XXE attacks. An authenticated user with access to the import endpoint can exploit this vulnerability, leading to unauthorized disclosure of server files and Server-Side Request Forgery (SSRF) attacks. The exploitation requires the targeted file to be shorter than 1023 characters.
Users can upgrade to OpenRemote version 1.22.0 or later, where this vulnerability has been addressed.
