Notebook replacement via encoded traversal note names
Published Apr 9, 2024 · Updated Mar 25, 2025
Authentication bypass in Apache Zeppelin 0.10.1 allows remote authenticated users to replace another user's notebook. NotebookService.normalizeNotePath checked a note name without first URL-decoding it, so encoded parent-directory segments bypassed traversal validation and resolved to an existing note path. A low-privilege account with notebook-creation access can overwrite notebook content owned by another user; the reported consequence is limited to integrity.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0.10.1 <0.11.0
