Summary

CVE-2026-3489 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 10.7th 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-2026-3489 is a SQL injection vulnerability in the DirectoryPress – Business Directory And Classified Ad Listing plugin for WordPress, affecting versions up to and including 3.6.26. The issue stems from insufficient escaping of the user-supplied 'packages' parameter and lack of sufficient preparation in the existing SQL query, allowing injection of malicious SQL code.

Unauthenticated attackers can exploit this vulnerability over the network with low attack complexity and no user interaction required. Successful exploitation enables appending 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.

Mitigation guidance is provided in the plugin's WordPress trac changeset at https://plugins.trac.wordpress.org/changeset/3474986/directorypress and Wordfence threat intelligence advisory at https://www.wordfence.com/threat-intel/vulnerabilities/id/2e602223-8571-42e1-9b3f-e7cc51f8fa58?source=cve.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SI-10 Information Input Validation good match
prevent

Directly requires validation of user-supplied inputs like the 'packages' parameter to prevent SQL injection by ensuring insufficient escaping and preparation issues are addressed.

SI-2 Flaw Remediation good match
prevent

Mandates timely flaw remediation, such as patching the DirectoryPress plugin up to version 3.6.26, to eliminate the SQL injection vulnerability.

SC-7 Boundary Protection partial match
preventdetect

Implements boundary protection, including web application firewalls, to inspect and block malicious SQL payloads targeting the vulnerable 'packages' parameter.
