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
An Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Apache Zeppelin allows logged-in users to execute arbitrary javascript in other users' browsers. This issue affects Apache Zeppelin before 0.8.2. Users are recommended to upgrade to a supported version of Zeppelin.

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 · high confidence

This is a stored XSS vulnerability in Apache Zeppelin where authenticated users can inject malicious JavaScript code that executes in other users' browsers when they view the compromised content. The vulnerability stems from improper input neutralization during web page generation.

MitigationUpgrade Apache Zeppelin to version 0.8.2 or later to receive the security patch. Before upgrading, review release notes for breaking changes and test in a staging environment.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if Apache Zeppelin is installed
    Check for Zeppelin processes (ps aux | grep zeppelin) or common installation directories such as /opt/zeppelin, /usr/local/zeppelin, or the Zeppelin home directory defined by ZEPPELIN_HOME environment variable.
    Affected if Apache Zeppelin process is running or installation directory exists on the system.
  2. Determine installed Zeppelin version
    Check the version file typically located at $ZEPPELIN_HOME/zeppelin-version.json or inspect the About page in the Zeppelin web UI (navigate to the user menu and select About).
    Affected if The version cannot be determined or is lower than 0.8.2.
  3. Compare version against affected range
    Review the identified version against the vulnerable range: Apache Zeppelin versions prior to 0.8.2 are affected by this stored XSS vulnerability.
    Affected if Installed version is 0.8.1 or lower, or any pre-0.8.2 release.
  4. Verify web interface accessibility
    Confirm the Zeppelin web UI is accessible by attempting to access the server on the configured port (default 8080 or 8443 for HTTPS). Check server configuration files (zeppelin-site.xml or zeppelin-env.sh) for bind addresses and port settings.
    Affected if The Zeppelin web interface is exposed and reachable over the network.

If Apache Zeppelin version 0.8.1 or any version below 0.8.2 is installed and running with its web interface accessible, the environment is affected by CVE-2022-46870 stored XSS vulnerability.

Upgrade available Upgrade to 0.8.2 or later
Fixed in 0.8.2
Interim mitigation

Upgrade Apache Zeppelin to version 0.8.2 or later to receive the security patch. Before upgrading, review release notes for breaking changes and test in a staging environment.

Recommended fix High confidence

0.8.2 or later

  1. 1. Stop the currently running Apache Zeppelin instance
  2. 2. Backup your existing Zeppelin configuration directory (typically /zeppelin/conf or the directory set in ZEPPELIN_HOME)
  3. 3. Backup your Zeppelin notebooks directory (typically /zeppelin/notebook)
  4. 4. Download Apache Zeppelin version 0.8.2 or later from the official Apache Zeppelin download page (https://zeppelin.apache.org/download.html)
  5. 5. Extract the new Zeppelin archive to your desired installation location
  6. 6. Copy your backed-up configuration files to the new installation's conf directory
  7. 7. Start the new Zeppelin instance
  8. 8. Verify that Zeppelin is running correctly and the web interface is accessible
