Raw vector
CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
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 39th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
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.

Security testing in development catches injection vulnerabilities before release.
Logging supports detection of injection attempts but does not prevent the weakness.
Monitoring activities can identify active injection attacks after they occur.
Secure development life cycle mandates input validation and output encoding that directly prevent injection flaws.
Application security requirements explicitly call for controls against injection attacks in software design.
Secure architecture principles reduce injection surfaces but do not prescribe specific neutralization techniques.
