CVE-2026-39470

Vulnerability

The WooCommerce Cart Abandonment Recovery plugin for WordPress versions prior to 2.1.0 contains a privilege escalation vulnerability [1]. A user with the Shop Manager role can exploit this flaw to elevate their privileges to a higher level, potentially reaching administrator access. The issue affects all sites running the plugin before the patched release.

Exploitation

An attacker must first obtain a valid Shop Manager account on the target WordPress site. With that access, they can trigger the vulnerability through an unspecified mechanism in the plugin's code, likely via a crafted request or manipulation of role capabilities. No additional user interaction or special network position beyond normal authenticated access is required [1].

Impact

Successful exploitation grants the attacker elevated privileges, enabling them to assume full control of the WordPress site. This includes the ability to modify content, install malicious plugins, exfiltrate sensitive data, and create new administrative accounts, effectively compromising the entire site [1].

Mitigation

The vulnerability is fixed in version 2.1.0 of the WooCommerce Cart Abandonment Recovery plugin. Users must update to this version or later immediately. For those unable to update, Patchstack offers a mitigation rule that blocks exploitation attempts until the patch is applied [1]. Administrators should also consider enabling automatic updates for vulnerable plugins.
