Technical Analysis

CVE-2025-49417 is a critical security vulnerability classified under CWE-502, which pertains to the deserialization of untrusted data. This vulnerability affects the BestWpDeveloper WooCommerce Product Multi-Action plugin, specifically versions up to 1.3. The core issue arises from the plugin's handling of serialized data, where untrusted input can be deserialized without proper validation or sanitization. This flaw enables an attacker to perform object injection attacks, potentially leading to remote code execution, privilege escalation, or complete system compromise. The vulnerability has a CVSS v3.1 base score of 9.8, indicating its critical severity. The vector metrics (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) reveal that the attack can be executed remotely over the network without any authentication or user interaction, and it impacts confidentiality, integrity, and availability at a high level. Although no known exploits are currently reported in the wild, the nature of the vulnerability and its ease of exploitation make it a significant threat. The absence of available patches at the time of reporting further exacerbates the risk. Given that WooCommerce is a widely used e-commerce platform on WordPress, and this plugin extends its functionality, the vulnerability could be leveraged to compromise online stores, steal sensitive customer data, manipulate product information, or disrupt business operations.

Potential Impact

For European organizations, especially those operating e-commerce platforms using WordPress and WooCommerce with the BestWpDeveloper WooCommerce Product Multi-Action plugin, this vulnerability poses a severe risk. Exploitation could lead to unauthorized access to customer data, including payment information, violating GDPR and other data protection regulations, potentially resulting in heavy fines and reputational damage. The integrity of product listings and pricing could be manipulated, causing financial losses and undermining customer trust. Availability impacts could disrupt online sales, leading to revenue loss and operational downtime. Given the critical nature of the vulnerability and the lack of authentication or user interaction requirements, attackers could automate exploitation attempts, increasing the likelihood of widespread attacks. Moreover, the potential for remote code execution could allow attackers to establish persistent backdoors within affected systems, facilitating further attacks or lateral movement within corporate networks. This threat is particularly concerning for small and medium-sized enterprises (SMEs) that may lack robust cybersecurity defenses and timely patch management processes.

Mitigation Recommendations

Immediate mitigation steps should include auditing all WordPress installations for the presence of the BestWpDeveloper WooCommerce Product Multi-Action plugin and identifying affected versions. Until an official patch is released, organizations should consider disabling or uninstalling the plugin to eliminate the attack surface. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block suspicious serialized payloads targeting the plugin's endpoints can provide interim protection. Monitoring web server logs for unusual POST requests or serialized data patterns can help detect exploitation attempts. Organizations should also enforce strict input validation and sanitization practices in custom code and plugins. Regular backups of website data and configurations should be maintained to enable rapid recovery in case of compromise. Once a patch becomes available, prompt testing and deployment are critical. Additionally, organizations should review user privileges and restrict administrative access to reduce the impact of potential exploitation. Educating website administrators about the risks of untrusted data deserialization and maintaining an inventory of all installed plugins will support proactive vulnerability management.
