CVE-2026-18653: CWE-89 SQL Injection in WP Directory Kit
The WP Directory Kit WordPress plugin before 1.5.7 does not sanitise and escape a parameter before using it in a SQL statement, allowing administrators to perform SQL injection attacks. On a multisite installation this lets an administrator of a single site read data belonging to the entire network, which they are not otherwise able to reach.
AI Analysis
Technical Summary
CVE-2026-18653 is an SQL injection vulnerability (CWE-89) in the WP Directory Kit WordPress plugin prior to version 1.5.7. The plugin fails to sanitize and escape a parameter before including it in a SQL query. This enables administrators on a multisite WordPress setup to execute SQL injection attacks, potentially reading data from the entire network, which they normally cannot access. The vulnerability has a CVSS 3.1 base score of 7.2, indicating high severity with network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker with administrator privileges on a single site within a multisite WordPress installation can exploit this vulnerability to perform SQL injection attacks. This can lead to unauthorized disclosure of data across the entire multisite network, compromising confidentiality. The integrity and availability of the affected system can also be impacted due to the nature of SQL injection.
Mitigation Recommendations
No official patch or remediation level has been confirmed yet. Users should monitor the vendor's advisory for updates and apply the official fix once available. Until then, restrict administrator privileges carefully and consider disabling or removing the WP Directory Kit plugin if multisite data exposure risk is unacceptable.
