CVE-2025-59007 is a deserialization of untrusted data vulnerability found in the TF Woo Product Grid Addon For Elementor plugin, which is used to enhance WooCommerce product grid displays within Elementor-built WordPress sites. The vulnerability arises because the plugin improperly handles serialized data inputs, allowing attackers to inject malicious objects during the deserialization process. This object injection can lead to remote code execution, data manipulation, or denial of service. The vulnerability affects all versions up to and including 1.0.1. The CVSS v3.1 score of 8.1 reflects a high-severity issue with network attack vector (AV:N), high attack complexity (AC:H), no privileges required (PR:N), no user interaction (UI:N), and impacts confidentiality, integrity, and availability (C:H/I:H/A:H). No patches or exploit code are currently publicly available, but the vulnerability is published and reserved as of September 2025. The flaw allows attackers to send crafted serialized payloads remotely, without authentication, to trigger unsafe deserialization, potentially compromising the entire WordPress environment hosting the plugin. This can lead to unauthorized data access, website defacement, or full system compromise.

For European organizations, this vulnerability poses a significant threat especially to those relying on WordPress-based e-commerce or marketing platforms using the TF Woo Product Grid Addon. Exploitation can lead to exposure of sensitive customer data, including personal and payment information, damaging brand reputation and violating GDPR compliance. The integrity of product listings and pricing could be manipulated, leading to financial losses or fraud. Availability impacts may cause website downtime, disrupting business operations and customer trust. Given the unauthenticated remote exploit vector, attackers can scan and compromise vulnerable sites en masse, increasing the risk of widespread attacks. The high attack complexity somewhat limits exploitation to skilled attackers, but the lack of required privileges or user interaction lowers barriers significantly. European organizations with limited patch management or monitoring capabilities are especially vulnerable to persistent threats and follow-on attacks such as ransomware or data exfiltration.

1. Immediately monitor for updates or patches from the vendor (themesflat) and apply them as soon as they become available. 2. Until patches are released, disable or remove the TF Woo Product Grid Addon plugin from production environments. 3. Implement Web Application Firewalls (WAF) with custom rules to detect and block suspicious serialized payloads or unusual POST requests targeting the plugin endpoints. 4. Conduct thorough input validation and sanitization on all user-supplied data, especially serialized inputs, to prevent unsafe deserialization. 5. Restrict access to WordPress admin and plugin endpoints via IP whitelisting or VPN where feasible. 6. Regularly audit WordPress installations for unauthorized changes or signs of compromise. 7. Educate site administrators on the risks of installing unverified plugins and maintaining timely updates. 8. Employ security plugins that can detect and quarantine malicious payloads or code injections. 9. Maintain comprehensive backups and incident response plans to recover quickly from potential exploitation. 10. Monitor threat intelligence feeds for emerging exploit code or attack campaigns targeting this vulnerability.
