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
Cross-Site Request Forgery (CSRF) vulnerability in Apache Zeppelin. The default CORS configuration allowed cross-origin state-changing requests and accepted text/plain request bodies, allowing an attacker who lures an authenticated user to a                   malicious site to perform actions on the user's behalf through REST and WebSocket endpoints. This issue affects Apache Zeppelin versions 0.6.0 through 0.12.0. Users are recommended to upgrade to version 0.12.1, which fixes this issue.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-352

The application can't tell whether a state-changing request was genuinely intended by the user, so an attacker can trick a logged-in victim's browser into making it. That can transfer funds, change settings, or create accounts silently. Remediation is anti-CSRF tokens — or equivalent same-site protections — on every state-changing request.

Upgrade available Upgrade to 0.12.1 or later
Fixed in 0.12.1
Recommended fix High confidence

Apache Zeppelin 0.12.1

  1. Download Apache Zeppelin version 0.12.1 from the official Apache Zeppelin release repository (https://zeppelin.apache.org/download.html)
  2. Stop the currently running Zeppelin instance
  3. Backup the Zeppelin directory and any custom configurations
  4. Extract the new 0.12.1 release to the desired installation location
  5. Migrate any custom configurations from the backup to the new installation
  6. Start the Zeppelin 0.12.1 service
  7. Verify the CORS configuration has been updated by checking the zeppelin-site.xml or equivalent configuration file
  8. Test that REST and WebSocket endpoints are functioning correctly with the new configuration
