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'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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-54640)\n\nAffected packages:\n\n- `io.openremote:openremote-agent <= 1.24.1`\n\nPatched in:\n\n- `io.openremote:openremote-agent 1.24.2`\n\nSource: https://github.com/advisories/GHSA-7v6w-c3f4-9wpq","depth":"twilight","depthScore":42,"depthScoreParts":{"impact":41.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
