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.

How this vulnerability can be exploited

This issue can be reached over the network, attack complexity is low, an attacker needs low-level privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity none, availability none.

CVSS metrics in full

The score comes from this vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N

  • Attack vector: Network — reachable from anywhere that can route to the service.
  • Attack complexity: Low — the attack works reliably, with no preparation.
  • Privileges required: Low — an ordinary user account is enough.
  • User interaction: None — nobody has to be tricked into anything.
  • Scope: Unchanged — the damage stays inside the vulnerable component.
  • Confidentiality impact: High — total loss, or loss the attacker controls.
  • Integrity impact: None.
  • Availability impact: None.

Weakness class

CVE-2026-44615 is classified as CWE-22: Path Traversal. A file path built from user input is not confined to the intended directory, letting an attacker reach files elsewhere on the filesystem.
