CVE-2026-4306
Published: 23 March 2026
Summary
CVE-2026-4306 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 12.4th 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-2026-4306 is a SQL injection vulnerability in the WP Job Portal plugin for WordPress, affecting all versions up to and including 2.4.8. The flaw arises from insufficient escaping of the user-supplied 'radius' parameter and lack of adequate preparation in existing SQL queries, allowing attackers to append malicious SQL payloads. It has been assigned a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) and maps to CWE-89 (Improper Neutralization of Special Elements used in an SQL Command).
Unauthenticated attackers can exploit this vulnerability remotely over the network with low complexity and no user interaction required. By injecting payloads via the 'radius' parameter, they can append additional SQL queries to extract sensitive information from the database, such as user credentials or other confidential data stored by the plugin.
References indicate the vulnerability in specific code locations, including ajax.php line 10 and model.php line 2743 in version 2.4.7. A changeset from version 2.4.8 to 2.4.9 documents the fix, suggesting that updating to 2.4.9 or later mitigates the issue. Additional details are available in the Wordfence threat intelligence advisory.

Why these techniques?
SQL injection in a public-facing WordPress plugin directly enables remote unauthenticated exploitation of an internet-facing application (T1190) to extract database contents such as credentials.

Mitigating Controls (NIST 800-53 r5) AI
SI-10 mandates information input validation at system entry points, directly addressing the insufficient escaping of the user-supplied 'radius' parameter that enables SQL injection.
SI-2 requires timely flaw remediation, such as patching the WP Job Portal plugin to version 2.4.9 or later where proper SQL query preparation fixes the vulnerability.
SC-7 enforces boundary protection at external interfaces, enabling web application firewalls to inspect and block SQL injection payloads in the 'radius' parameter.
