CVE-2025-48266 is a medium severity vulnerability classified under CWE-79, indicating an Improper Neutralization of Input During Web Page Generation, commonly known as Cross-site Scripting (XSS). This vulnerability affects the RealMag777 Active Products Tables plugin for WooCommerce, specifically versions up to 1.0.6.8. The flaw allows an attacker to inject malicious scripts that are stored persistently (Stored XSS) within the plugin's data handling processes. When a victim accesses the affected web pages generated by the plugin, the malicious script executes in their browser context. The CVSS 3.1 base score of 6.5 reflects a scenario where the attack vector is network-based (AV:N), requires low attack complexity (AC:L), but does require privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects components beyond the vulnerable module, and the impact affects confidentiality, integrity, and availability to a limited extent (C:L/I:L/A:L). Stored XSS vulnerabilities can lead to session hijacking, defacement, redirection to malicious sites, or unauthorized actions performed on behalf of the victim. Since this vulnerability resides in a WooCommerce plugin, it targets WordPress e-commerce sites using this plugin to display active product tables, potentially exposing customers and administrators to malicious script execution. No known exploits are reported in the wild yet, and no patches are currently linked, indicating that mitigation might require vendor updates or manual intervention.

For European organizations, especially those operating e-commerce platforms using WooCommerce with the RealMag777 Active Products Tables plugin, this vulnerability poses a significant risk. Exploitation could lead to customer data theft, session hijacking, and unauthorized transactions, undermining customer trust and potentially violating GDPR due to data confidentiality breaches. The integrity of product listings and pricing could be compromised, leading to financial losses and reputational damage. Availability impacts, while limited, could disrupt user experience and sales. Given the widespread adoption of WooCommerce in Europe, particularly among small and medium enterprises (SMEs), the threat surface is considerable. Attackers exploiting this vulnerability could target high-traffic retail sites, causing cascading effects on supply chains and consumer confidence. Additionally, regulatory scrutiny in Europe means that organizations failing to address such vulnerabilities risk fines and legal consequences.

1. Immediate mitigation involves disabling or removing the RealMag777 Active Products Tables plugin until a vendor patch is released. 2. Implement strict input validation and output encoding on all user-supplied data within the plugin's scope to neutralize malicious scripts. 3. Employ Content Security Policy (CSP) headers to restrict script execution sources and reduce XSS impact. 4. Conduct thorough code reviews and penetration testing focusing on the plugin's data handling and rendering logic. 5. Monitor web server logs and user reports for suspicious activities indicative of XSS exploitation attempts. 6. Educate site administrators and users about the risks of clicking unknown links or executing unexpected actions. 7. Once a patch is available, prioritize timely updates and verify the fix through testing. 8. Consider deploying Web Application Firewalls (WAFs) with rules targeting XSS payloads as an interim protective measure. These steps go beyond generic advice by focusing on plugin-specific controls, proactive monitoring, and layered defense strategies.
