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 News & Blog Designer Pack – WordPress Blog Plugin — (Blog Post Grid, Blog Post Slider, Blog Post Carousel, Blog Post Ticker, Blog Post Masonry) plugin for WordPress is vulnerable to Remote Code Execution via Local File Inclusion in all versions up to, and including, 3.4.1 via the bdp_get_more_post function hooked via a nopriv AJAX. This is due to function utilizing an unsafe extract() method to extract values from the POST variable and passing that input to the include() function. This makes it possible for unauthenticated attackers to include arbitrary PHP files and achieve remote code execution. On vulnerable Docker configurations it may be possible for an attacker to create a PHP file and then subsequently include it to achieve RCE.

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.

How this class of weakness works · CWE-98

A PHP include or require path is built from user-controlled input, so an attacker can steer it to a remote URL or an unintended local file — and because the target is then executed as code, this often becomes remote code execution. It is the classic remote/local file-inclusion trap. The fix is never to build include paths from input: map requests to a fixed allow-list of includable files.

Upgrade available Upgrade to a release after 3.4.1
Recommended fix High confidence

Plugin version > 3.4.1 (check WordPress plugin repository for latest fixed release)

  1. Navigate to Plugins > Installed Plugins in the WordPress admin dashboard
  2. Locate 'News & Blog Designer Pack' in the plugin list
  3. Check the current version installed (should be <= 3.4.1)
  4. Update the plugin to the latest available version from the WordPress plugin repository
  5. Verify the update was successful and the plugin is now running a version newer than 3.4.1
  6. If auto-update is not enabled, consider enabling it or regularly checking for updates
