CVE-2024-13921 is a PHP Object Injection vulnerability (CWE-502) affecting the Order Export & Order Import for WooCommerce plugin for WordPress in all versions up to and including 2.6.0. The issue arises from deserialization of untrusted input via the 'form_data' parameter, enabling authenticated attackers with Administrator-level access or higher to inject a PHP Object. The vulnerability carries a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) and was published on 2025-03-20.
Exploitation requires an authenticated attacker with at least Administrator privileges. While the vulnerability allows PHP Object injection, no known Proof-of-POP (Property-Oriented Programming) chain exists within the vulnerable plugin itself, rendering it ineffective in isolation. Impact only materializes if another plugin or theme on the target site provides a POP chain, potentially enabling actions such as arbitrary file deletion, sensitive data retrieval, or code execution, depending on the chain available.
Advisories and references, including Wordfence threat intelligence and WordPress plugin trac repositories, point to the vulnerable code in the export and import AJAX classes (class-export-ajax.php and class-import-ajax.php). A patch is indicated via changeset 3258567 in the plugin's trac, suggesting mitigation through updating to a version beyond 2.6.0.

Vulnerability Data
The Order Export & Order Import for WooCommerce plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.6.0 via deserialization of untrusted input from the 'form_data' parameter. This makes it possible for authenticated…
more
attackers, with Administrator-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can uncover deserialization flaws before deployment.
Input validation directly stops deserialization of untrusted data by ensuring inputs are valid before processing.
Engineering principles such as safe deserialization and input sanitization structurally prevent the weakness from being introduced.
Integrity verification tools can detect malformed or tampered serialized data after the fact.

PR.PS-02 addresses only post-deployment updates/patching and cannot prevent introduction of unsafe deserialization code, yet it can remediate some instances when the flaw exists in outdated libraries or components.

Security testing includes validation of deserialization routines and the use of untrusted data, reducing the likelihood that unsafe object reconstruction will be deployed.
Requiring vetted libraries, regular updates and SAST before release reduces the likelihood that deserialization logic will accept and act on attacker-controlled serialized objects.
Regular scanning of third-party libraries and timely patching reduce the likelihood that unsafe deserialization vulnerabilities remain active.
Mandatory malware scanning of data received over networks or storage media intercepts malicious serialized payloads before they are deserialized by the target application.
