AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Nonce gate is trivially bypassed via a nopriv endpoint so PR:N holds; remote low-complexity arbitrary file read gives C:H with no integrity or availability impact.

The Printcart Web to Print Product Designer for WooCommerce plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 2.8.5 via the 'mockups' parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information. A valid nonce is obtainable by unauthenticated users via the companion nbd_check_use_logged_in nopriv AJAX endpoint, which freely mints and returns a nbdesigner-get-data nonce to any visitor; additionally, if the NBDESIGNER_ENABLE_NONCE constant is disabled, even this nonce gate is bypassed entirely.
AnalysisAI
Unauthenticated directory traversal in the Printcart Web to Print Product Designer for WooCommerce WordPress plugin (all versions up to and including 2.8.5) allows remote attackers to read arbitrary files on the underlying server by manipulating the 'mockups' parameter, exposing configuration files, wp-config.php-style secrets, and other sensitive data. The traversal is gated only by a 'nbdesigner-get-data' nonce, but that nonce is freely minted to anonymous visitors by the plugin's own nbd_check_use_logged_in nopriv AJAX endpoint, and the check disappears entirely if the NBDESIGNER_ENABLE_NONCE constant is disabled, so authentication requirements are effectively nil (CVSS 3.1 base 7.5, AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitable when the Printcart Web to Print Product Designer for WooCommerce plugin (<=2.8.5) is installed and active on an internet-reachable WordPress/WooCommerce site. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine high-priority issue for exposed WooCommerce storefronts. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | No vendor-released patched version number is confirmed for CVE-2026-14323 - all releases through 2.8.5 remain affected, and the referenced Trac changeset 3658512 is an upstream code change rather than a verified fixed release. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all WordPress deployments using Printcart Web to Print Product Designer for WooCommerce versions up to and including 2.8.5 and either disable the plugin or apply a WAF rule blocking directory traversal payloads to the 'mockups' parameter and restricting access to the 'nbdesigner-get-data' AJAX endpoint and nopriv nonce-minting endpoint; rotate any secrets that may have been exposed. …
