CVE-2026-2019
Published: 18 February 2026
Summary
CVE-2026-2019 is a high-severity Injection (CWE-74) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.2 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 7.0th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2026-2019 is a code injection vulnerability affecting the Cart All In One For WooCommerce plugin for WordPress in all versions up to and including 1.1.21. The flaw stems from insufficient input validation on the 'Assign page' field, which is passed directly to the PHP eval() function, enabling arbitrary code execution. It has a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H) and is associated with CWE-74 (Improper Neutralization of Special Elements used in an SQL Command).
Authenticated attackers with Administrator-level access or higher can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows execution of arbitrary PHP code on the affected server, potentially leading to high-impact compromise of confidentiality, integrity, and availability.
Advisories and patch references, including Wordfence threat intelligence and WordPress plugin trac repositories, point to the vulnerable code in includes/frontend/sidebar-cart-icon.php at line 245 in version 1.1.21. Mitigation is addressed in changeset 3455202, which security practitioners should review for patching details, with updates available in the plugin trunk.

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of all inputs before they are passed to dangerous functions such as eval(), eliminating the root cause of the code-injection flaw.
Mandates prompt application of vendor patches (changeset 3455202) that remove the unsanitized eval() call in sidebar-cart-icon.php.
Limits the number of accounts granted Administrator privileges, thereby reducing the population that can reach the vulnerable 'Assign page' field.
