The Printcart Web to Print Product Designer for WooCommerce plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 2.5.2 This is due to insufficient path validation in the store_design_data() function, which constructs a filesystem path from the user-supplied 'nbd_item_key' POST parameter sanitized only with sanitize_text_field() - which does not strip path traversal sequences - and then passes that path directly to Nbdesigner_IO::delete_folder() and PHP's rename(). The nonce protecting the nbd_save_customer_design AJAX action is freely obtainable by unauthenticated users via the nbd_check_use_logged_in endpoint. This makes it possible for unauthenticated attackers to delete arbitrary files on the affected site's server which may make remote code execution possible.

AnalysisAI
Arbitrary file deletion in the Printcart Web to Print Product Designer for WooCommerce WordPress plugin (versions up to and including 2.5.2) lets unauthenticated attackers delete any file on the server, potentially escalating to remote code execution. The store_design_data() function builds a filesystem path from the attacker-controlled 'nbd_item_key' POST value and the nonce guarding the AJAX action can be freely retrieved by anonymous users, so exploitation needs no login. No public exploit has been identified at time of analysis, but the network-reachable, no-privilege profile makes this a high-priority patch.
Technical ContextAI
The affected component is the Printcart (nbdesigner / printcart-integration) plugin that adds a web-to-print product designer to WooCommerce storefronts. The root cause is CWE-22 (Improper Limitation of a Pathname to a Restricted Directory / path traversal): the 'nbd_item_key' parameter is passed only through WordPress's sanitize_text_field(), which trims tags and whitespace but does NOT neutralize '../' traversal sequences. That unsanitized value is concatenated into a filesystem path and handed to the plugin's Nbdesigner_IO::delete_folder() helper and PHP's native rename(), allowing the path to escape the intended design-storage directory. The CPE cpe:2.3:a:printcart:printcart_web_to_print_product_designer_for_woocommerce confirms the single affected plugin package.
RemediationAI
Vendor-released patch: update the plugin to version 2.5.3, which is the first fixed release per the WordPress plugin trac changeset (https://plugins.trac.wordpress.org/changeset?old_path=%2Fprintcart-integration/tags/2.5.2&new_path=%2Fprintcart-integration/tags/2.5.3); review the Wordfence advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/5bb962bd-9b23-4820-885e-d8095250c3c7?source=cve) for confirmation. If immediate patching is not possible, deactivate and remove the Printcart plugin until it can be updated (this disables the vulnerable nbd_save_customer_design AJAX action but also removes web-to-print functionality from the store), or place a WAF/virtual-patch rule that blocks POST requests to admin-ajax.php for the nbd_save_customer_design action containing '../' or encoded traversal sequences in the nbd_item_key parameter (risk of breaking legitimate design saves if key formats vary). As defense in depth, run PHP under a least-privilege user and enforce filesystem permissions so the web server cannot delete files outside the uploads/design directory.
