CVE-2026-53698Network attack vector

Authenticated arbitrary file read via absolute path

Published Jun 10, 2026 · Updated Jun 10, 2026

Absolute path traversal in Silverpeas 6.4.6 and earlier allows remote authenticated users to read arbitrary server files. The FileServer servlet treats an omitted ComponentId as Personal space, then honors TypeUpload by marking the SourceFile path absolute before sending the resolved file. A valid low-privilege session is required, and successful exploitation discloses any file readable by the Silverpeas server process without modifying it.
