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 WP Photo Album Plus is installed
    Check the WordPress plugins directory (wp-content/plugins) for a folder named 'wp-photo-album-plus' or query the WordPress database wp_options table for the plugin option entry
    Affected if The plugin folder or database entry exists
  2. Determine the installed plugin version
    Open the main plugin file (wp-photo-album-plus/wp-photo-album-plus.php) and locate the version comment header, or check the plugin readme.txt file
    Affected if The version string shows 8.7.01.001 or lower
  3. Confirm the plugin is active
    Query the WordPress database wp_options table where option_name='active_plugins', or check through WordPress admin plugins list
    Affected if The plugin is currently activated on the site
  4. Verify upload directory permissions and existence
    Inspect the WordPress uploads folder (wp-content/uploads) and check if it is writable by the web server user
    Affected if The uploads directory exists and is writable (required for exploit)
  5. Scan for suspicious uploaded files
    Search wp-content/uploads and subdirectories for files with extensions .php, .phtml, .php5, .php7, .phar, or other executable extensions that were recently created
    Affected if Unexpected executable files exist in upload directories

You are affected if WP Photo Album Plus is installed, active, and running version 8.7.01.001 or lower with a writable uploads directory.
