Summary

CVE-2026-2468 is a high-severity SQL Injection (CWE-89) vulnerability in Wordpress (inferred from references). Its CVSS base score is 7.5 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 27.5th 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 RA-5 (Vulnerability Monitoring and Scanning) and SI-10 (Information Input Validation).

Deeper analysis

CVE-2026-2468 is a SQL injection vulnerability (CWE-89) in the Quentn WP plugin for WordPress, affecting all versions up to and including 1.2.12. The issue arises in the `get_user_access()` method within the `class-quentn-wp-restrict-access.php` file, where the 'qntn_wp_access' cookie parameter is not sufficiently escaped or prepared before being appended to an existing SQL query.

Unauthenticated attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required. By manipulating the cookie, they can inject additional SQL queries to extract sensitive information from the database. The CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) reflects high confidentiality impact with no integrity or availability disruption.

Advisories and code analysis are detailed in references from Wordfence threat intelligence and WordPress plugin trac repositories, including the vulnerable code at line 483 in version 1.2.12 and the trunk branch. These sources provide context for remediation through patching or configuration review.
