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 ShortPixel Adaptive Images plugin is installed
    Log in to WordPress admin dashboard, navigate to Plugins > Installed Plugins, and look for 'ShortPixel Adaptive Images' in the list. Alternatively, check the /wp-content/plugins/ directory for a folder named 'shortpixel-adaptive-images'.
    Affected if The plugin is found in the WordPress installation.
  2. Determine installed plugin version

    Affected if The site is reachable from the internet or untrusted networks.
  4. Check if plugin functionality is active
    Visit the WordPress site frontend and inspect whether images are being processed through ShortPixel (look for ShortPixel CDN URLs in image src attributes). Alternatively, check plugin settings at Settings > ShortPixel to confirm the plugin is enabled.
    Affected if The plugin is active and processing images on the site.
