CVE-2026-7411Public exploitNetwork attack vector

Unauthenticated file write via unsanitized upload filename

Published May 5, 2026 · Updated May 5, 2026

Path traversal in Eclipse BaSyx Java Server SDK before 2.0.0-milestone-10 allows remote attackers to write arbitrary host files. SubmodelServiceHTTPApiController passes the fileName upload parameter through createUniqueFileName, which concatenates it into a repository path without normalization or boundary checks. Network access to the Submodel HTTP API and an existing Submodel File element are required; writable startup or credential files can yield code execution as the Java process.
