CVE-2025-64379 identifies a missing authorization vulnerability in the Pluggabl Booster for WooCommerce plugin, specifically versions up to 7.4.0. This plugin extends WooCommerce functionality, widely used in WordPress-based e-commerce sites. The vulnerability arises due to incorrectly configured access control security levels, allowing users with limited privileges (PR:L) to access certain functionalities or data without proper authorization checks. The CVSS 3.1 score of 4.3 (medium) reflects that the attack vector is network-based (AV:N), requires low attack complexity (AC:L), and privileges (PR:L) but no user interaction (UI:N). The impact is limited to confidentiality (C:L) with no integrity (I:N) or availability (A:N) impact. This means an attacker could potentially read data they should not have access to but cannot modify or disrupt services. No known exploits are currently in the wild, and no patches have been released yet. The vulnerability affects the Booster for WooCommerce plugin, a popular add-on that enhances WooCommerce capabilities, making it relevant for many online stores. The issue was reserved and published in late 2025, indicating recent discovery and disclosure. The lack of patches necessitates immediate attention to access controls and monitoring until a fix is available.

For European organizations, especially e-commerce businesses relying on WooCommerce with the Booster plugin, this vulnerability could lead to unauthorized disclosure of sensitive business or customer data. While it does not allow data modification or service disruption, exposure of confidential information could harm customer trust, violate data protection regulations such as GDPR, and potentially lead to compliance penalties. Attackers with limited privileges, such as low-level employees or compromised accounts, could exploit this flaw remotely without user interaction, increasing the risk of stealthy data leaks. The impact is more pronounced for organizations with weak internal access controls or where the plugin is widely used to manage critical e-commerce functions. This vulnerability could also be leveraged as a foothold for further attacks if combined with other vulnerabilities. Given the importance of e-commerce in Europe and the strict regulatory environment, even medium-severity confidentiality breaches warrant prompt mitigation.

1. Monitor official Pluggabl and WooCommerce channels for the release of a security patch addressing CVE-2025-64379 and apply it immediately upon availability. 2. In the interim, audit and tighten user roles and permissions within WordPress and WooCommerce to ensure that only trusted users have access to Booster plugin functionalities. 3. Implement additional access control mechanisms such as web application firewalls (WAFs) to detect and block unauthorized access attempts targeting the plugin. 4. Conduct regular security reviews and penetration testing focusing on plugin access controls to identify and remediate misconfigurations. 5. Limit network exposure of administrative interfaces and restrict access to trusted IP ranges where feasible. 6. Enable detailed logging and monitoring of plugin-related activities to detect suspicious behavior early. 7. Educate staff about the risks of privilege misuse and enforce strong authentication methods to reduce the risk of account compromise. 8. Consider temporarily disabling or restricting the Booster plugin if the risk is deemed unacceptable until a patch is applied.
