Missing Authorization vulnerability in EDGARROJAS Extra Product Options Builder for WooCommerce additional-product-fields-for-woocommerce allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Extra Product Options Builder for WooCommerce: from n/a through <= 1.2.167.
AnalysisAI
Missing authorization in the Extra Product Options Builder for WooCommerce plugin (versions through 1.2.167) permits remote unauthenticated attackers to perform restricted actions without valid credentials, impacting both data integrity and service availability on affected WordPress storefronts. The flaw stems from CWE-862 - the plugin exposes endpoints or AJAX actions that fail to verify whether the caller holds the necessary capability or role before executing sensitive operations. No public exploit code has been identified at time of analysis, and the vulnerability has not been listed in the CISA KEV catalog.
Technical ContextAI
The affected component is a WordPress plugin (slug: additional-product-fields-for-woocommerce) developed by EDGARROJAS, designed to extend WooCommerce product pages with configurable extra fields and options. Under the WordPress/WooCommerce security model, privileged operations - such as modifying product option configurations - should be gated by capability checks (e.g., current_user_can()) and nonce validation. CWE-862 (Missing Authorization) indicates the plugin omits these checks on one or more endpoints, allowing any HTTP client to invoke privileged functionality. The CPE string cpe:2.3:a:edgarrojas:extra_product_options_builder_for_woocommerce:*:*:*:*:*:*:*:* confirms the vulnerability spans the entire release history up to and including version 1.2.167.
RemediationAI
The primary fix is to update the Extra Product Options Builder for WooCommerce plugin to any version released after 1.2.167; however, no exact patched version number is confirmed in the available input data - administrators should consult the WordPress plugin repository or the Patchstack advisory at https://patchstack.com/database/Wordpress/Plugin/additional-product-fields-for-woocommerce/vulnerability/wordpress-extra-product-options-builder-for-woocommerce-plugin-1-2-167-broken-access-control-vulnerability for the confirmed fixed release before upgrading. If an update is not immediately available, a compensating control is to temporarily deactivate the plugin to remove the exposed endpoints from the attack surface - this disables extra product option functionality but eliminates the authorization bypass risk. Alternatively, a Web Application Firewall rule blocking unauthenticated POST requests to the plugin's AJAX handlers (typically wp-admin/admin-ajax.php with the plugin's specific action parameters) can reduce exposure while preserving authenticated use, though WAF rule tuning may require site-specific testing to avoid disrupting legitimate customer flows.
