Incorrect Privilege Assignment vulnerability in wpweb WooCommerce PDF Vouchers woocommerce-pdf-vouchers allows Privilege Escalation.This issue affects WooCommerce PDF Vouchers: from n/a through < 4.9.9.

AnalysisAI

Privilege escalation in the WooCommerce PDF Vouchers WordPress plugin (wpweb) affects all versions up to and including 4.9.8, allowing remote unauthenticated attackers to gain elevated privileges on affected sites due to incorrect privilege assignment. With a CVSS score of 9.8 and EPSS at the 90th percentile (5.34%), this represents a meaningful threat to WordPress sites running this plugin, though no public exploit identified at time of analysis. The vulnerability was reported by Patchstack and impacts the full confidentiality, integrity, and availability triad of affected WordPress installations.

Technical ContextAI

The vulnerability resides in the WooCommerce PDF Vouchers plugin (CPE: cpe:2.3:a:wpwebelite:woocommerce_pdf_vouchers), a WordPress extension for WooCommerce that enables merchants to sell and manage PDF-based gift vouchers. The root cause is classified as CWE-266 (Incorrect Privilege Assignment), meaning the plugin assigns privileges to users or roles in a manner that does not respect the principle of least privilege - typically via flawed capability checks, missing authorization logic on AJAX/REST endpoints, or improper role assignment during user registration or voucher redemption flows. Because the plugin integrates with WordPress's role and capability system as well as WooCommerce's customer/order model, a defect in how it grants or validates privileges can promote a low-privileged or anonymous actor to a higher role such as administrator.

RemediationAI

Upgrade the WooCommerce PDF Vouchers plugin to version 4.9.9 or later, which is the first version not flagged in the affected range - patch availability inferred from the version cutoff stated in the advisory (Patch available per vendor advisory). Until the upgrade is applied, administrators should consider deactivating the WooCommerce PDF Vouchers plugin (this disables voucher sales and redemption functionality but eliminates the attack surface), restricting access to the WordPress site's REST and admin-ajax endpoints via WAF rules to block unauthenticated requests touching plugin routes (note this may break legitimate front-end voucher purchase flows), and auditing existing user accounts for unexpected administrator or shop_manager roles that may indicate prior exploitation. After patching, rotate administrative credentials and review WordPress audit logs.
