Unauthenticated file deletion via trash operation
Published Dec 16, 2022 · Updated Apr 17, 2025
Improper input validation in Apache Zeppelin 0.9.0 and earlier allows remote attackers to delete arbitrary server files. Apache has identified the Move folder to Trash feature as the affected locus but has not published the input field, path-handling operation, or validation failure that lets a request escape the intended notebook scope. No authentication or user interaction is required, and the reported consequence is limited to deletion of files accessible to the Zeppelin server process.
