CVE-2026-7859
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 · uneditedThe Motors WordPress plugin before 1.4.110 does not have proper authorisation and CSRF checks on one of its AJAX actions, allowing unauthenticated attackers to modify arbitrary post metadata, such as the gallery, featured image and, on WooCommerce sites, product prices.
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 confidenceThe Motors WordPress plugin before 1.4.110 lacks proper authorization enforcement and CSRF validation on an AJAX action endpoint. This allows unauthenticated attackers to send crafted requests that modify arbitrary post metadata, including gallery images, featured images, and notably WooCommerce product prices on affected e-commerce sites.

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 Motors plugin installation and versionCheck the installed version of the Motors plugin in WordPress. Common locations: wp-content/plugins/stm-motors/ or wp-content/plugins/motors-car-dealership/. You can also use: grep -r 'Version:' wp-content/plugins/*/style.css 2>/dev/null | grep -i motors, or check via WordPress admin under Plugins > Installed Plugins.Affected if The Motors plugin is installed with a version number lower than 1.4.110 (e.g., 1.4.100, 1.4.90, etc.)
-
Determine if WooCommerce is activeCheck if WooCommerce is enabled on the WordPress site. Use: wc_get_products(array('limit' => 1)) via WP CLI or check wp_woocommerce_session_ table exists in the database, or view active plugins list.Affected if WooCommerce is active alongside a vulnerable version of Motors, making product price manipulation possible via the vulnerability.
-
Locate the vulnerable AJAX action handlerExamine the Motors plugin files for AJAX handlers that handle post metadata updates. Search for add_action('wp_ajax_') or add_action('wp_ajax_nopriv_') calls that handle meta/update operations. Look in plugin main file or includes/ajax.php. The vulnerable action likely involves stm_listing_ or stm_ajax_ prefixes.Affected if An AJAX endpoint accessible to unauthenticated users (wp_ajax_nopriv_ or no capability check) handles metadata updates for posts.
-
Verify the endpoint lacks authorization checksReview the AJAX handler code identified in step 3. Check if the function verifies user capabilities (current_user_can) or implements nonce validation before updating post meta. Look for missing check_admin_referer or wp_verify_nonce calls.Affected if The AJAX handler does not verify user permissions or validate nonces before allowing metadata modifications.
-
Test metadata modification without authenticationSend a crafted POST request to wp-admin/admin-ajax.php with the identified action (e.g., action=stm_listing_update_meta) and meta fields (e.g., _price, _regular_price for WooCommerce products). Example: curl -X POST 'https://yoursite.com/wp-admin/admin-ajax.php' -d 'action=stm_xxx&post_id=123&meta_key=_price&meta_value=0'Affected if The request successfully modifies post metadata without authentication, confirming the vulnerability is exploitable.
Your environment is affected if the Motors plugin version is below 1.4.110 AND the vulnerable unauthenticated AJAX endpoint exists AND lacks proper authorization/CSRF checks, especially if WooCommerce is active.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpdate the Motors plugin to version 1.4.110 or later to obtain the vendor patch. If an update is unavailable, consider disabling the plugin or implementing web application firewall rules to block unauthorized metadata modification requests.
Motors plugin version 1.4.110
- Log in to the WordPress admin dashboard
- Navigate to Plugins > Installed Plugins
