CVE-2026-2019 is a code injection vulnerability categorized under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component) found in the Cart All In One For WooCommerce plugin for WordPress. The vulnerability exists in all versions up to and including 1.1.21 due to insufficient input validation on the 'Assign page' field. This field's input is passed directly to the PHP eval() function, which executes the input as PHP code. Because eval() executes arbitrary PHP code, an attacker with authenticated Administrator-level access or higher can inject and execute malicious PHP code on the server hosting the WordPress site. This can lead to full server compromise, including data theft, website defacement, installation of backdoors, or pivoting to other network systems. The vulnerability requires high privileges (Administrator or above) but does not require user interaction, and the attack can be performed remotely over the network. The CVSS v3.1 score is 7.2, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity and no user interaction needed. No patches or exploit code are currently publicly available, but the vulnerability's nature makes it a critical concern for affected sites. The plugin is widely used in WooCommerce environments, which are popular in e-commerce platforms worldwide, including Europe.

For European organizations, the impact of this vulnerability is significant, especially for those operating e-commerce websites using WooCommerce with the Cart All In One plugin. Successful exploitation can lead to complete server compromise, resulting in theft of sensitive customer data (including payment information), disruption of online sales, reputational damage, and potential regulatory penalties under GDPR for data breaches. The ability to execute arbitrary PHP code allows attackers to install malware, create persistent backdoors, or manipulate website content, severely affecting business continuity. Given the widespread use of WooCommerce in European markets, particularly in countries with mature e-commerce sectors, the risk extends to a broad range of small to medium enterprises and larger retailers. The vulnerability's requirement for administrator-level access somewhat limits exploitation to insiders or attackers who have already compromised lower-level accounts, but privilege escalation or credential theft could facilitate this. The lack of known exploits in the wild currently reduces immediate risk but does not eliminate the threat, as weaponization could occur rapidly once details are publicized.

1. Immediate removal or disabling of the Cart All In One For WooCommerce plugin until a patched version is released. 2. Restrict administrator access strictly to trusted personnel and enforce strong authentication mechanisms, including multi-factor authentication (MFA). 3. Conduct regular audits of administrator accounts and monitor logs for suspicious activity indicative of privilege misuse or code injection attempts. 4. Implement Web Application Firewall (WAF) rules to detect and block attempts to inject PHP code via the 'Assign page' field or other plugin inputs. 5. Use security plugins that can detect unauthorized changes to PHP files or unusual code execution patterns. 6. Keep WordPress core, themes, and all plugins updated to their latest versions to reduce exposure to known vulnerabilities. 7. Employ principle of least privilege for all user roles to minimize the risk of privilege escalation. 8. Prepare incident response plans specific to web application compromise scenarios to enable rapid containment and recovery. 9. Once a patch is available, apply it promptly and verify the fix through testing in a staging environment before production deployment.
