{"id":"CVE-2026-54640","published":"2026-10-13T17:17:41.490","lastModified":"2026-10-16T20:04:29.760","description":"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.","cvssScore":7.6,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L","cwes":["CWE-611"],"vendors":[],"products":[],"references":[{"url":"https://github.com/openremote/core/commit/c28d3c60ebc2da68d9b6c4a6d7a5ad875a255ee9","tags":[]},{"url":"https://github.com/openremote/core/releases/tag/1.24.2","tags":[]},{"url":"https://github.com/openremote/core/security/advisories/GHSA-7v6w-c3f4-9wpq","tags":[]}],"exploitRefs":[{"url":"https://github.com/openremote/core/commit/c28d3c60ebc2da68d9b6c4a6d7a5ad875a255ee9","tags":[]},{"url":"https://github.com/openremote/core/releases/tag/1.24.2","tags":[]},{"url":"https://github.com/openremote/core/security/advisories/GHSA-7v6w-c3f4-9wpq","tags":[]}],"hasPoc":true,"ai":null}
