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
Cloudera Hue Ace Editor Directory Traversal Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Cloudera Hue. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Ace Editor web application. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose information in the context of the service account. Was ZDI-CAN-24332.

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 · moderate confidence

Cloudera Hue's Ace Editor component contains a directory traversal vulnerability due to insufficient validation of user-supplied file paths. An unauthenticated remote attacker can manipulate path traversal sequences (e.g., ../) in file operation requests to escape the intended directory and read sensitive files on the host system, potentially exposing configuration files, credentials, or other confidential data in the context of the service account running Hue.

MitigationApply vendor-provided patches for CVE-2025-3884. As an interim control, restrict network access to the Hue service and implement Web Application Firewall rules to block path traversal patterns in request parameters.

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 Hue installation and version
    Check the Hue installation directory for version information. Common locations: /opt/cloudera/hue or check package manager (dpkg -l | grep hue, rpm -qa | grep hue). Look for a version file or check the Hue UI login page footer for the version number.
    Affected if The installed Hue version is exactly 4.11.0
  2. Confirm Ace Editor is in use
    Hue uses Ace Editor for code editing features. Identify if any Hue applications that use the Ace Editor component (SQL editors, file browser, code editors) are enabled and accessible. Check Hue configuration files (hue.ini) for enabled apps.
    Affected if Ace Editor is enabled and accessible through any Hue application interface
  3. Check network exposure
    Determine if the Hue web interface is exposed to untrusted networks. Review firewall rules, load balancer configurations, or cloud security groups controlling access to the Hue port (usually 8888). Check if Hue binds to 0.0.0.0 or an external interface.
    Affected if Hue is accessible from untrusted network segments or the internet without authentication barriers
  4. Look for path traversal exploitation indicators
    Review Hue access logs for suspicious patterns containing ../ sequences in file path parameters. Search for patterns like '..%2F', '..%252F', or literal '../' in request URLs. Check for access to sensitive files outside expected directories.
    Affected if Logs show path traversal attempts or unauthorized access to system files outside the Hue sandbox directory

You are affected if Hue version 4.11.0 is running, Ace Editor is accessible, and the service is network-accessible to potential attackers.
