{"id":"CVE-2026-54640","summary":"OpenRemote: XXE in KNXProtocol.startAssetImport() allows arbitrary file read via unprotected XMLInputFactory","details":"OpenRemote is an open-source internet-of-things platform. 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.","aliases":["GHSA-7v6w-c3f4-9wpq"],"modified":"2026-10-14T10:30:22.257171247Z","published":"2026-10-13T16:02:21.245Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54640.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-611"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54640.json"},{"type":"FIX","url":"https://github.com/openremote/core/commit/c28d3c60ebc2da68d9b6c4a6d7a5ad875a255ee9"},{"type":"WEB","url":"https://github.com/openremote/core/releases/tag/1.24.2"},{"type":"ADVISORY","url":"https://github.com/openremote/core/security/advisories/GHSA-7v6w-c3f4-9wpq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54640"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openremote/core","events":[{"introduced":"0"},{"fixed":"c312ee8b2a7ccd0bda6a42b6ba26a5c7ab44a6d0"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.24.2"}],"source":"AFFECTED_FIELD"}}],"versions":["1.24.1","1.24.0","1.23.1","1.23.0","1.22.1","1.22.0","1.21.0","1.20.2","1.20.1","1.20.0","1.19.0","1.18.0","1.17.3","1.17.2","1.17.1","1.17.0","1.16.1","1.16.0","1.15.2","1.15.1","1.15.0","1.14.0","1.13.1","1.13.0","1.12.3","1.12.2","1.12.1","1.12.0","1.11.3","1.11.2","1.11.1","1.11.0","1.10.0","1.9.0","1.8.1","1.8.0","archive/console_loader","1.7.0","1.6.5","1.6.4","1.6.3","1.6.2","1.6.1","1.6.0","1.5.0","1.4.0","1.3.5","1.3.4","1.3.3","1.3.2","1.3.1","1.3.0","1.2.4","1.2.3","1.2.2","1.2.1","1.2.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54640.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L"}]}
