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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L","score":7.6},"cwes":["CWE-611"],"references":["https://github.com/openremote/core/commit/c28d3c60ebc2da68d9b6c4a6d7a5ad875a255ee9","https://github.com/openremote/core/releases/tag/1.24.2","https://github.com/openremote/core/security/advisories/GHSA-7v6w-c3f4-9wpq"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:58:52.678897993+00:00"},"epss":{"cve":"CVE-2026-54640","score":0.00219,"percentile":0.12329,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-7v6w-c3f4-9wpq","url":"https://osv.dev/vulnerability/GHSA-7v6w-c3f4-9wpq","summary":"OpenRemote has an incomplete fix for CVE-2026-40882: XXE in KNXProtocol.startAssetImport() allows arbitrary file read via unprotected XMLInputFactory","modified":"2026-07-06T21:11:32.012240Z","packages":[{"ecosystem":"Maven","name":"io.openremote:openremote-agent","purl":"pkg:maven/io.openremote/openremote-agent","ranges":["<1.24.2"],"fixed":["1.24.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
