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 All-in-One Video Gallery plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the resolve_import_directory() function in versions 4.5.4 to 4.5.7. This makes it possible for authenticated attackers, with Author-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

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 All-in-One Video Gallery WordPress plugin versions 4.5.4 through 4.5.7 contains an arbitrary file upload vulnerability in the resolve_import_directory() function due to missing file type validation. Authenticated attackers with Author-level or higher permissions can upload arbitrary files to the server, potentially achieving remote code execution.

MitigationUpdate the plugin to version 4.5.8 or later. If patching is not immediately possible, restrict or disable the import functionality and monitor for suspicious uploads.

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 All-in-One Video Gallery plugin is installed
    Check the WordPress plugins directory or access wp-admin > Plugins to see if 'All-in-One Video Gallery' is listed as an active or installed plugin
    Affected if The plugin is present in the WordPress installation
  2. Check the installed plugin version
    Navigate to Plugins > Installed Plugins > All-in-One Video Gallery and compare the version number to the affected range 4.5.4 through 4.5.7
    Affected if The installed version is 4.5.4, 4.5.5, 4.5.6, or 4.5.7
  3. Verify if Author-level or higher user roles exist
    Navigate to Users > All Users in wp-admin and review the role assigned to each user; check for any users with Author, Editor, or Administrator roles
    Affected if At least one user account has Author role or higher privileges
  4. Confirm if the import functionality is accessible
    Look for the video import feature in the plugin settings (typically under All-in-One Video Gallery > Import or a similar menu) and verify it can be accessed by Author-level users
    Affected if The import functionality is enabled and accessible to users with Author permissions

A user is affected if the All-in-One Video Gallery plugin version is between 4.5.4 and 4.5.7 inclusive AND at least one user with Author-level or higher permissions exists with access to the import feature.
