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. Verify Blocksy Companion Pro plugin is installed
    Check the WordPress plugins directory at wp-content/plugins/ for a folder named 'blocksy-companion-pro' or 'ct-companion', or log into WordPress admin and view the installed plugins list
    Affected if The plugin appears in the installed plugins list or filesystem
  2. Identify the installed version of Blocksy Companion Pro
    In WordPress admin, go to Plugins > Installed Plugins and find the version number listed under the Blocksy Companion Pro plugin description, or inspect the main plugin file (e.g., blocksy-companion-pro.php) for the 'Version' header in the plugin comments
    Affected if A version number is displayed or found in the plugin files
  3. Compare the installed version to the affected range
    Compare the discovered version number to 2.1.46 using standard version comparison (e.g., 2.1.46, 2.1.45, 2.1.40, 2.0.10 are all <= 2.1.46)
    Affected if The installed version is 2.1.46 or any earlier version (e.g., 2.1.45, 2.1.0, 1.9.0)
  4. Confirm the Pro variant is in use
    This vulnerability affects the Pro version specifically. Check if the installed package is 'blocksy-companion-pro' rather than the free 'blocksy-companion' version, or verify the plugin is labeled as Pro in the WordPress admin plugins list
    Affected if The Blocksy Companion Pro (paid) version is installed

If Blocksy Companion Pro is installed and the version is 2.1.46 or lower, the environment is vulnerable to unauthenticated remote code execution.
