CVE-2026-79653Network attack vector

Authenticated arbitrary file write via upload filename

Published Aug 27, 2026 · Updated Aug 27, 2026

Path traversal in Eclipse SW360 19.0.0 through 19.2.0, 20.0.0, and 20.1.0 allows remote authenticated users to write files outside storage. The attachment-upload path passes an attacker-controlled filename to filesystem storage without confining the resolved path to the configured attachment directory. Exploitation requires a low-privileged account and the optional filesystem attachment store, which is disabled by default; uploads can place files at host paths writable by the service.
