CVE-2026-44615 Details
Description
Path traversal vulnerability in Apache Zeppelin. When FileSystemNotebookRepo is configured, an authenticated attacker with permission to rename a note, or access to folder operations, could supply traversal segments in note or folder paths. Zeppelin composed these values into filesystem paths using the server's filesystem or Hadoop identity without ensuring that the result remained under the configured notebook directory. This could allow notebook files or directories to be moved, written, or deleted outside the notebook root. This issue affects Apache Zeppelin versions 0.9.0 through 0.12.0. Users are recommended to upgrade to version 0.12.1, which fixes this issue.
A path traversal vulnerability exists in Apache Zeppelin versions 0.9.0 prior to 0.12.1, specifically when the FileSystemNotebookRepo is enabled. This vulnerability allows an authenticated attacker with permission to rename notes or access folder operations to manipulate note or folder paths by injecting traversal segments. Zeppelin fails to validate these paths, potentially allowing files or directories to be moved, written, or deleted outside the designated notebook directory.
Users are advised to upgrade to Apache Zeppelin version 0.12.1, which addresses this vulnerability.
