CVE-2025-12570 is a stored cross-site scripting vulnerability classified under CWE-79 found in the Fancy Product Designer plugin for WordPress, affecting all versions up to and including 6.4.8. The vulnerability stems from insufficient sanitization and escaping of user-supplied SVG file uploads processed by the plugin’s data-to-image.php and pdf-to-image.php scripts. An attacker can upload a crafted SVG file containing malicious JavaScript code that is stored on the server and executed in the context of any user who views the SVG file, including site administrators or customers. This attack vector does not require authentication or user interaction, increasing its risk profile. The vulnerability impacts confidentiality and integrity by enabling script execution that could lead to session hijacking, data theft, or further exploitation of the victim’s browser environment. The CVSS 3.1 score of 7.2 reflects a high severity due to network attack vector, low attack complexity, no privileges required, no user interaction, and a scope change affecting other components beyond the vulnerable plugin. No patches were linked at the time of disclosure, and no known exploits have been reported in the wild. The vulnerability is particularly relevant for e-commerce and product customization websites using this plugin, as SVG uploads are common in these contexts. Detection and mitigation require careful inspection of SVG upload handling, enhanced input validation, and output encoding to prevent script injection.

For European organizations, this vulnerability poses a significant risk, especially for those operating e-commerce platforms or websites that utilize the Fancy Product Designer plugin for product customization. Exploitation could lead to unauthorized script execution in users’ browsers, resulting in session hijacking, theft of sensitive customer data, or manipulation of website content. This can damage brand reputation, lead to regulatory non-compliance under GDPR due to data breaches, and cause financial losses. The vulnerability’s unauthenticated and no user interaction exploitation vector increases the likelihood of automated attacks or mass exploitation campaigns. Given the widespread use of WordPress and the popularity of product customization plugins in Europe’s robust e-commerce sector, the potential attack surface is considerable. Additionally, the scope change indicated by the CVSS score suggests that the impact could extend beyond the plugin itself, potentially affecting other integrated systems or user sessions. Organizations may also face increased scrutiny from regulators and customers if exploited, emphasizing the need for prompt mitigation.

1. Monitor official channels from the vendor (radykal) for patches or updates addressing CVE-2025-12570 and apply them immediately upon release. 2. Until patches are available, disable or restrict SVG file uploads within the Fancy Product Designer plugin or WordPress media library to trusted users only. 3. Implement strict server-side validation and sanitization of SVG files to remove or neutralize embedded scripts before processing or storing them. 4. Employ Content Security Policy (CSP) headers to restrict the execution of inline scripts and reduce the impact of potential XSS payloads. 5. Conduct regular security audits and scanning of uploaded SVG files for malicious content using specialized tools. 6. Educate site administrators and developers about the risks of SVG uploads and ensure secure coding practices are followed when handling user-generated content. 7. Consider isolating or sandboxing SVG rendering components to limit the scope of any potential script execution. 8. Monitor web server and application logs for unusual access patterns or errors related to SVG processing that may indicate exploitation attempts. 9. Use Web Application Firewalls (WAFs) with updated rules to detect and block malicious payloads targeting this vulnerability. 10. Review and tighten user permissions related to file uploads and plugin management to reduce attack surface.
