CVE-2025-1913 is a deserialization vulnerability classified under CWE-502 found in the Product Import Export for WooCommerce – Import Export Product CSV Suite plugin for WordPress. The vulnerability arises from unsafe deserialization of the 'form_data' parameter, which accepts serialized PHP objects. An attacker with Administrator-level privileges can inject malicious PHP objects through this parameter. However, the vulnerability's exploitability depends on the presence of a Property Oriented Programming (POP) chain in other installed plugins or themes, which can be leveraged to perform malicious actions such as arbitrary file deletion, sensitive data retrieval, or remote code execution. The plugin itself does not contain a POP chain, so the vulnerability is a prerequisite condition rather than a standalone exploit. The CVSS 3.1 score of 7.2 indicates a high severity with network attack vector (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality (C:H), integrity (I:H), and availability (A:H). No known exploits are currently in the wild, but the vulnerability was published on March 26, 2025. The affected versions include all versions up to and including 2.5.0. This vulnerability is particularly relevant for WordPress sites running WooCommerce with this plugin installed alongside other plugins or themes that contain exploitable POP chains.

For European organizations, this vulnerability poses a significant risk to e-commerce platforms using WooCommerce with the vulnerable plugin. If exploited, attackers could gain the ability to execute arbitrary code, delete critical files, or exfiltrate sensitive customer and business data, leading to data breaches, service disruption, and reputational damage. The requirement for Administrator-level access limits the attack surface but does not eliminate risk, especially in environments with multiple administrators or compromised credentials. The dependency on additional plugins or themes for a POP chain means that organizations with complex WordPress setups are at higher risk. Given the critical role of e-commerce in European markets, successful exploitation could disrupt business operations and violate data protection regulations such as GDPR, resulting in legal and financial consequences.

1. Immediately update the Product Import Export for WooCommerce plugin to a patched version once available. 2. Audit all installed plugins and themes for known POP chains or unsafe deserialization patterns; remove or update any that are vulnerable. 3. Restrict Administrator-level access strictly to trusted personnel and enforce strong authentication mechanisms, including multi-factor authentication. 4. Implement Web Application Firewalls (WAF) with rules to detect and block suspicious serialized payloads or unusual POST requests targeting the 'form_data' parameter. 5. Regularly monitor logs for anomalous activity related to plugin usage and deserialization attempts. 6. Employ security plugins that can detect and prevent PHP Object Injection attacks. 7. Conduct regular security assessments and penetration tests focusing on WordPress plugin vulnerabilities. 8. Educate administrators on the risks of installing untrusted plugins or themes that may introduce POP chains.
