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
When users add resources to the resource center with a relation path will cause path traversal issues and only for logged-in users. You could upgrade to version 3.0.0 or higher

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

A path traversal vulnerability exists in the resource center feature where users can add resources using a relation path, allowing attackers to access files outside the intended directory. This occurs due to insufficient input validation on the path parameter when adding resources, and the vulnerability is only exploitable by authenticated (logged-in) users.

MitigationUpgrade to version 3.0.0 or higher to receive the patch that addresses the path traversal vulnerability in the resource center functionality.

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. Confirm Apache Dolphinscheduler installation
    Identify the installed Dolphinscheduler version by checking the version file, startup logs, or administrative UI. Common locations include the 'conf' directory configuration files or the UI footer displaying the version number.
    Affected if The installed version is anything less than 3.0.0 (e.g., 2.x.x series)
  2. Verify resource center feature is accessible
    Log in as an authenticated user and navigate to the resource center module in the Dolphinscheduler web interface. Check if the 'Resource Center' or 'Resources' tab is visible and accessible to regular users.
    Affected if The resource center feature is enabled and accessible to authenticated users (non-admin users can access the resource management functionality)
  3. Check resource file upload/add functionality
    In the resource center interface, locate the option to add or upload resources. Observe if there is a path parameter or file selection mechanism that allows specifying custom paths for resource relations.
    Affected if The resource add/upload interface accepts custom path input without strict validation or displays a path traversal capability
  4. Review resource storage configuration
    Examine the Dolphinscheduler configuration files (commonly in conf/ or properties files) for the resource.base.path or similar resource storage directory setting. This defines where resources are stored.
    Affected if Resources are stored in a configurable directory path that could be manipulated via path traversal input
  5. Assess user permissions to resource center
    Check the user role assignments and permissions configuration to determine which authenticated users have access to creating or modifying resources in the resource center.
    Affected if Non-administrative authenticated users have create or upload permissions in the resource center

A user is affected if they run Apache Dolphinscheduler version below 3.0.0 with the resource center feature enabled and accessible to authenticated users who can add resources with custom path input.

Upgrade available Upgrade to 3.0.0 or later
Fixed in 3.0.0
Interim mitigation

Upgrade to version 3.0.0 or higher to receive the patch that addresses the path traversal vulnerability in the resource center functionality.

Recommended fix Moderate confidence

3.0.0

  1. Review current Dolphinscheduler installation and confirm current version is below 3.0.0
  2. Review the official Apache DolphinScheduler 3.0.0 release notes and upgrade guide for breaking changes
  3. Create a backup of the current DolphinScheduler database and configuration files
  4. Test the upgrade in a staging environment before applying to production
  5. Stop the DolphinScheduler services
  6. Upgrade DolphinScheduler to version 3.0.0 or later using the appropriate installation method (upgrade tool, helm, or docker)
  7. Verify the upgrade was successful by checking the version number
  8. Test that the path traversal vulnerability is resolved by attempting to add a resource with a relative path containing ../ sequences
