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
Featured Image from Content (featured-image-from-content) WordPress plugin versions prior to 1.7 contain an authenticated server-side request forgery vulnerability that allows Author-level users to fetch internal HTTP resources. Attackers can exploit insecure URL fetching and file write operations to retrieve sensitive internal data and store it in web-accessible upload directories.

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 featured-image-from-content WordPress plugin versions before 1.7 contains an authenticated server-side request forgery (SSRF) vulnerability. Attackers with Author-level privileges can exploit insecure URL fetching to make the server request internal HTTP resources (such as localhost, intranet endpoints, or cloud metadata services) and write the retrieved sensitive data to web-accessible upload directories.

MitigationUpdate the featured-image-from-content plugin to version 1.7 or later, which patches the insecure URL fetching functionality. Additionally, restrict Author-level user permissions and monitor for suspicious internal resource requests.

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. Verify the plugin is installed
    Navigate to WordPress admin > Plugins and look for 'featured-image-from-content' in the installed plugins list
    Affected if The plugin appears in the installed plugins list and is activated
  2. Check the installed plugin version
    Click on the plugin in the WordPress plugins list or check the plugin header in wp-content/plugins/featured-image-from-content/featured-image-from-content.php for the Version comment
    Affected if The installed version is below 1.7 (such as 1.6.x or earlier)
  3. Confirm Author-level or higher users exist
    Go to WordPress admin > Users and review user roles. Author role and above (Editor, Administrator) can exploit this vulnerability
    Affected if At least one user account has Author, Editor, or Administrator role enabled on the site
  4. Inspect plugin URL fetching configuration
    Check the plugin settings page (usually under Settings > Featured Image from Content) for any URL input fields or external URL fetching options, and review the plugin source code for fetch_url or wp_remote_get function calls
    Affected if The plugin contains URL fetching functionality that accepts user-supplied URLs without proper validation
  5. Review access logs for internal resource requests
    Examine server access logs (Apache/nginx error and access logs) for requests to internal IPs (127.0.0.1, 10.x.x.x, 192.168.x.x), localhost, or cloud metadata endpoints (169.254.169.254) originating from the WordPress site
    Affected if Suspicious requests to internal network addresses appear in logs with user agent matching WordPress or the plugin

A user is affected if the featured-image-from-content plugin versions before 1.7 is installed and active, and at least one Author-level or higher user account exists on the WordPress site.

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

Update the featured-image-from-content plugin to version 1.7 or later, which patches the insecure URL fetching functionality. Additionally, restrict Author-level user permissions and monitor for suspicious internal resource requests.

Recommended fix High confidence

version 1.7

  1. Update the Featured Image from Content (featured-image-from-content) WordPress plugin to version 1.7 or later via the WordPress admin dashboard under Plugins > Installed Plugins
  2. Verify the update was successful by confirming the plugin version displays as 1.7 or higher
  3. Confirm that Author-level users can no longer make arbitrary HTTP requests to internal resources through the plugin's URL fetching functionality
