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 Twitter posts to Blog plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'dg_tw_options' function in all versions up to, and including, 1.11.25. This makes it possible for unauthenticated attackers to update plugin settings including Twitter API credentials, post author, post status, and the capability required to access the plugin's admin menu.

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 Twitter posts to Blog WordPress plugin has a Broken Access Control vulnerability where the 'dg_tw_options' function lacks capability verification, allowing unauthenticated attackers to modify critical plugin settings including Twitter API credentials, post authorship, and post publication status.

MitigationUpdate the plugin to the latest patched version. If no patch is available, restrict access to the affected endpoint via web server configuration or deploy a WAF rule to block unauthorized POST requests to the vulnerable function until a fix is released.

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 plugin installation
    Check for the presence of the Twitter posts to Blog plugin in wp-content/plugins/ directory or view it in WordPress admin under Plugins
    Affected if Plugin is installed and active
  2. Determine installed version
    Look up the plugin version in the plugin header comment in the main PHP file (typically dg_twitter_to_blog.php or similar) or in WordPress admin plugin list
    Affected if Version is within any known affected range or cannot be determined (treat as potentially vulnerable)
  3. Identify vulnerable endpoint exposure
    Check if the dg_tw_options AJAX action is publicly accessible by testing a POST request to /wp-admin/admin-ajax.php with action=dg_tw_options (no authentication required for the check itself)
    Affected if Endpoint responds without requiring login/authentication
  4. Verify settings modification access
    Attempt a test POST to the dg_tw_options endpoint with a harmless parameter to see if the server accepts it without a valid nonce or capability check
    Affected if Server accepts and processes the request without returning an authentication error or capability verification failure

A user is affected if the Twitter posts to Blog plugin is active and the dg_tw_options endpoint accepts unauthenticated requests, allowing settings modification without WordPress capability verification
