At a glance

CVE-2025-0956 is a high-severity Deserialization of Untrusted Data vulnerability in the WooCommerce Recover Abandoned Cart WordPress plugin, affecting versions <= 24.4.0. It carries a CVSS score of 8.1 (reachable over the network; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 24.5.0; sites on affected versions should update now. Disclosed March 2025, reported by Lucio Sá.

Vulnerability Overview

The WooCommerce Recover Abandoned Cart plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 24.4.0 via deserialization of untrusted input from the 'raccookie_guest_email' cookie. This makes it possible for unauthenticated attackers 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.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.

CWE-502: Deserialization of Untrusted Data

WooCommerce Recover Abandoned Cart <= 24.4.0 carries this weakness at raccookie_guest_email, and reaching it takes no account at all. Deserialization of untrusted data means the application reconstructs objects from input a caller controls, letting the attacker choose which classes get instantiated and what their properties hold.

A workable chain turns deserialization into file writes, deletions or code execution, depending on what the loaded classes do in their magic methods. For WooCommerce Recover Abandoned Cart the fix is 24.5.0: builds <= 24.4.0 are affected, anything from 24.5.0 onward is not.

Remediation

Update to version 24.5.0, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: WooCommerce Recover Abandoned Cart 24.5.0 closes this, and updating the plugin is the step that ends it.
