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 · moderate confidence

The fliperrr Creates 3D Flipbook, PDF Flipbook WordPress plugin (versions <= 1.2) contains an unrestricted file upload vulnerability that allows authenticated attackers to upload dangerous file types (such as web shells) directly to the web server, potentially achieving remote code execution and full server compromise.

MitigationRestrict file uploads to only allow safe file types (PDF, images), implement server-side MIME type and extension validation, rename uploaded files, store uploads outside the web root, and update to a patched version when 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. Identify if the fliperrr plugin is installed
    In the WordPress admin dashboard, navigate to Plugins > Installed Plugins and look for 'fliperrr Creates 3D Flipbook, PDF Flipbook' or check the /wp-content/plugins/ directory for a folder containing 'fliperrr' in the name
    Affected if The plugin is present on the WordPress site
  2. Determine the installed plugin version
    In WordPress admin, click on the plugin to view its details and locate the version number, or inspect the plugin's main PHP file for a 'Version' header comment
    Affected if The installed version is 1.2 or any version lower than 1.2
  3. Verify if file upload functionality is accessible
    Locate the upload endpoint or feature used by the plugin (typically found in plugin settings or frontend flipbook creation forms) and confirm it accepts file uploads
    Affected if The file upload feature exists and is accessible to authenticated users (any logged-in user)
  4. Check authentication requirements for uploads
    Test the upload functionality with a low-privilege WordPress user account (subscriber level) to confirm whether authentication alone is sufficient to access the upload feature
    Affected if Any authenticated user (regardless of role/privilege) can access and use the file upload feature

The environment is affected if the fliperrr plugin version 1.2 or lower is installed and its file upload feature is accessible to authenticated users without restrictive validation.
