Path traversal vulnerability in Apache Zeppelin. (CVE-2026-44615)
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.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-44615) affects Apache Zeppelin when FileSystemNotebookRepo is configured. The application improperly constructs filesystem paths from user-supplied note or folder paths without ensuring these paths remain within the configured notebook directory. An authenticated user with rename or folder operation permissions can supply path traversal sequences to manipulate files or directories outside the notebook root, potentially leading to unauthorized file modifications. The vulnerability affects versions 0.9.0 through 0.12.0 and is resolved in version 0.12.1.
Potential Impact
An attacker with authenticated access and specific permissions can move, write, or delete files outside the notebook root directory. This can lead to unauthorized modification or deletion of files on the server filesystem, potentially impacting confidentiality and integrity of data stored outside the intended directory. The CVSS score of 6.5 (medium severity) reflects the network attack vector with low complexity and no user interaction required, but limited to users with certain privileges.
Mitigation Recommendations
Users should upgrade Apache Zeppelin to version 0.12.1 or later, where this path traversal vulnerability is fixed. No other mitigations are indicated or required once the upgrade is applied.
