Prior to 1.24.2, the KNXProtocol.startAssetImport method in agent/src/main/java/org/openremote/agent/protocol/knx/KNXProtocol.java processes 0.xml from an authenticated user&#39;s uploaded ETS project ZIP with Saxon TransformerFactoryImpl and XMLInputFactory parsers that permit external entity resolution. This incomplete remediation of CVE-2026-40882 leaves the KNX handler unprotected while the parallel Velbus handler is hardened, allowing a regular realm user to read files accessible to the JVM process or cause server-side requests. This issue is fixed in version 1.24.2.</p> <p>OpenRemote is an open-source internet-of-things platform.

The KNX asset import handler (`KNXProtocol`) processes user-uploaded ETS project ZIP files through Saxon XSLT and `XMLInputFactory.newInstance()` with no XXE protection, allowing any authenticated user to read arbitrary files from the server filesystem (e.g. `/etc/passwd`, `openmrs-runtime.properties`, cloud credential files).</p> <p>### Details ### Incomplete patch</p> <p>CVE-2026-40882 was fixed by introducing `createSecureDocumentBuilderFactory()` in `AbstractVelbusProtocol.java` with five XXE-blocking features.
