CVE-2025-67929 identifies a missing authorization vulnerability in the TI WooCommerce Wishlist plugin developed by templateinvaders, affecting all versions up to and including 2.10.0. This vulnerability arises from incorrectly configured access control security levels, allowing users with limited privileges (PR:L) to perform unauthorized actions within the plugin's functionality. The attack vector is local (AV:L), meaning the attacker must have some level of authenticated access to the system or application environment, but no user interaction (UI:N) is required to exploit the flaw. The vulnerability impacts the confidentiality, integrity, and availability of the affected system, though to a limited degree (C:L/I:L/A:L). Specifically, an attacker could potentially access or modify wishlist data or related user information without proper authorization, possibly leading to data leakage or unauthorized changes that could disrupt normal e-commerce operations. The scope is unchanged (S:U), indicating the exploit affects only the vulnerable component without extending to other system components. No public exploits have been reported yet, and no patches are currently linked, suggesting that organizations should monitor for updates from the vendor. The vulnerability is particularly relevant for WooCommerce-based e-commerce websites that use the TI WooCommerce Wishlist plugin, which is popular among online retailers for wishlist functionality. Given the nature of the vulnerability, attackers with some authenticated access could leverage this flaw to escalate privileges or manipulate user data, potentially undermining customer trust and business operations.

For European organizations, the impact of CVE-2025-67929 could include unauthorized access to customer wishlist data, leading to potential privacy violations under GDPR. Integrity of wishlist and related user data could be compromised, affecting customer experience and trust. Availability impacts, while limited, could disrupt e-commerce operations if attackers modify or delete wishlist information. Given the medium severity and requirement for some privilege level, the risk is higher for organizations with many user roles or where privilege separation is weak. Retailers relying heavily on WooCommerce and the TI WooCommerce Wishlist plugin could face reputational damage and regulatory scrutiny if customer data is exposed or manipulated. The vulnerability could also be leveraged as a stepping stone for further attacks within the e-commerce platform, increasing overall risk. European e-commerce sectors, especially in countries with large online retail markets, could see targeted exploitation attempts once public exploits emerge.

Organizations should immediately inventory their WooCommerce installations to identify if the TI WooCommerce Wishlist plugin version 2.10.0 or earlier is in use. Until a patch is released, restrict access to the plugin’s administrative and wishlist management interfaces to trusted users only, employing role-based access controls to minimize privilege exposure. Implement monitoring and alerting for unusual activity related to wishlist data modifications or access patterns. Regularly audit user permissions to ensure least privilege principles are enforced. Consider disabling the wishlist functionality temporarily if it is not critical to business operations. Stay informed on vendor advisories and apply patches promptly once available. Additionally, web application firewalls (WAFs) can be tuned to detect and block suspicious requests targeting wishlist endpoints. Conduct security awareness training for administrators to recognize potential exploitation signs. Finally, ensure that backup and recovery procedures are robust to restore data integrity if unauthorized changes occur.
