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 checksWork through these to decide whether this CVE applies to you.
-
Confirm IDX IMPress Listings plugin is installedLog in to WordPress admin panel and navigate to Plugins > Installed Plugins, or inspect the /wp-content/plugins/ directory for the impress-listings folderAffected if The plugin is present on the WordPress site
-
Determine installed plugin versionIn WordPress admin, go to Plugins > Installed Plugins and locate IDX IMPress Listings to view the version number, or check the main plugin file (usually impress-listings.php) for the 'Version' headerAffected if The version shown is lower than 2.6.3
-
Verify vulnerable endpoint access existsReview the plugin directories (typically /wp-content/plugins/impress-listings/includes/) for PHP files that handle admin actions or data access; check if these files include current_user_can() or capability checks before executing sensitive operationsAffected if Files performing database queries, settings changes, or data retrieval lack proper authorization checks (no current_user_can(), wp_verify_nonce(), or similar validation)
-
Inspect AJAX and admin-ajax handlersSearch plugin files for do_action('wp_ajax_') or do_action('wp_ajax_nopriv_') calls; verify if these handlers include capability verification before processing requestsAffected if AJAX endpoints accept requests without verifying user permissions or nonce validation
The site is affected if IDX IMPress Listings version is below 2.6.3 and the plugin exposes functionality without proper capability checks.
