Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Missing Origin Validation in WebSockets vulnerability in Apache Zeppelin. The attacker could access the Zeppelin server from another origin without any restriction, and get internal information about paragraphs.  This issue affects Apache Zeppelin: from 0.11.1 before 0.12.0. Users are recommended to upgrade to version 0.12.0, which fixes the issue.

Recommended fix High confidence

0.12.0

  1. 1. Back up your Zeppelin configuration, data, and any custom interpreters to a secure location
  2. 2. Stop the Zeppelin service gracefully to avoid data corruption
  3. 3. Download Apache Zeppelin version 0.12.0 from the official Apache repository (https://zeppelin.apache.org/download.html)
  4. 4. Extract the new version and migrate your configuration files from the backup to the new installation
  5. 5. Verify that the WebSocket origin validation fix from PR #4823 is included in version 0.12.0
  6. 6. Start the Zeppelin service and verify it runs without errors
  7. 7. Test WebSocket connections from different origins to confirm the origin validation is now enforced
Caveat Review release notes for 0.12.0 for any configuration or feature changes that may affect your existing notebooks or workflows
