Description
The Fancy Product Designer plugin for WordPress is vulnerable to Stored Cross-Site Scripting via 'productTitle' in '_fpd_data' Order Item Meta in all versions up to, and including, 6.5.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The fpd_save_order AJAX action is registered for unauthenticated users via wp_ajax_nopriv_fpd_save_order with no nonce or capability check, and the strip_tags() sanitization applied at save time is bypassed by submitting JSON unicode escape sequences (e.g. \u003c, \u003e), which json_decode() silently converts back to literal angle brackets when the order is rendered in the admin view.

AI Analysis

Impact

The Fancy Product Designer WordPress plugin is vulnerable to stored cross‑site scripting due to unsanitized productTitle data in order item meta. An unauthenticated attacker can inject arbitrary JavaScript that runs whenever a user views an order in the admin interface. This can lead to defacement, cookie theft, session hijacking, or other malicious activities. The flaw is a CWE‑79 unsafe return of content to the browser.

Affected Systems

The vulnerability affects all installations of the Fancy Product Designer plugin by radykal that are version 6.5.2 or earlier. Administrators running these versions on WordPress sites should evaluate their installation.

Risk and Exploitability

The CVSS score of 7.2 reflects the high potential for exploitation and loss of confidentiality, integrity, or availability. Although no EPSS score is available, the lack of a nonce or capability check in the fpd_save_order AJAX endpoint enables attackers to submit malicious payloads from any network. The vulnerability is not listed in the CISA KEV catalog, but the attack path is simple and not restricted to privileged users. Administrators should treat the exposure as high risk and prioritize remediation.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade the Fancy Product Designer plugin to the latest version (6.5.3 or newer) that removes the vulnerability.
  • If an upgrade is temporarily impossible, block unauthenticated access to the fpd_save_order AJAX endpoint using a firewall or by adding a rule in .htaccess or nginx to deny wp_ajax_nopriv_fpd_save_order.
  • Deploy a web application firewall rule to scrub and block payloads containing JSON‑escaped angle brackets such as \u003c and \u003e before they reach the plugin.
  • Ensure that any administrative pages are accessible only to users with proper credentials and that session cookies are marked secure and HttpOnly.
