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
The Post Grid Gutenberg Blocks for News, Magazines, Blog Websites – PostX plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the '/ultp/v2/get_dynamic_content/' REST API endpoint in all versions up to, and including, 5.0.3. This makes it possible for unauthenticated attackers to retrieve sensitive user metadata, including password hashes.

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

The PostX WordPress plugin has a missing capability check on the `/ultp/v2/get_dynamic_content/` REST API endpoint, allowing unauthenticated attackers to retrieve sensitive user metadata including password hashes. This is a broken access control vulnerability where the REST API endpoint does not verify user permissions before returning data.

MitigationAdd a capability check (such as `current_user_can('edit_posts')` or similar appropriate capability) to the REST API endpoint `/ultp/v2/get_dynamic_content/` to ensure only authorized users can access user metadata. Alternatively, update to the latest plugin version if a security patch is available.

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 PostX plugin is installed
    Navigate to WordPress Admin > Plugins and verify PostX plugin is installed and active
    Affected if PostX plugin is present and active in the WordPress installation
  2. Identify installed PostX version
    Go to Plugins > Installed Plugins > PostX and record the version number. Compare this against the version that includes the security patch (check plugin changelog or security advisory for the fixed version)
    Affected if Running a version prior to the patched release
  3. Test unauthenticated REST API access
    Send a GET request to /wp-json/ultp/v2/get_dynamic_content/ using curl or a browser without providing any authentication credentials
    Affected if The endpoint responds with HTTP 200 and returns data without requiring login
  4. Verify sensitive data exposure
    Examine the API response payload. Look for user metadata fields such as password hashes, user emails, or other sensitive user information
    Affected if The endpoint returns user metadata including password hashes to unauthenticated requests

If the /ultp/v2/get_dynamic_content/ endpoint is accessible without authentication and returns user metadata such as password hashes, the environment is affected by this vulnerability.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Add a capability check (such as `current_user_can('edit_posts')` or similar appropriate capability) to the REST API endpoint `/ultp/v2/get_dynamic_content/` to ensure only authorized users can access user metadata. Alternatively, update to the latest plugin version if a security patch is available.

Recommended fix High confidence

PostX version 5.0.4 or later

  1. Log in to the WordPress admin dashboard
  2. Navigate to Plugins > Installed Plugins
  3. Find 'PostX' (Post Grid Gutenberg Blocks) in the plugin list
  4. If an update is available, click 'Update Now' to update to the latest version (5.0.4 or higher)
  5. Alternatively, download the latest version from wordpress.org/plugins/post-grid-gutenberg-blocks/ and upload it manually via Plugins > Add New > Upload Plugin
  6. After updating, verify the REST API endpoint '/ultp/v2/get_dynamic_content/' is no longer accessible without authentication
