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 Recently plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the fetch_external_image() function in versions up to, and including, 3.0.4. This makes it possible for authenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

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 Recently plugin is installed
    Navigate to WordPress admin dashboard > Plugins section and look for 'Recently' or 'Recently Project Recently' in the list of installed plugins
    Affected if The plugin appears in the installed plugins list
  2. Identify the installed version
    In the Plugins list, click on 'Recently' to view plugin details, or check the plugin's main PHP file (recently.php) for the 'Version' header comment in the plugin metadata
    Affected if The displayed version number is lower than 3.0.5 (e.g., 3.0.4, 3.0.3, etc.)
  3. Verify the vulnerable function exists
    Access the WordPress site via FTP or file manager, locate wp-content/plugins/recently/recently.php or includes/class-recently.php, and search for the function fetch_external_image()
    Affected if The function fetch_external_image() exists in the plugin code, indicating the vulnerable code path is present
  4. Confirm authentication method availability
    Determine if user registration is enabled or if there are existing user accounts with at least Contributor-level access by checking Users > All Users in WordPress admin
    Affected if Non-admin user accounts exist or user registration is open, meaning authenticated users could potentially trigger the vulnerable function

You are affected if the Recently plugin version is below 3.0.5 and the fetch_external_image() function is present in your installation, making arbitrary file upload possible for any authenticated user.
