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 a SQL injection vulnerability (CWE-89) in the WP Directory Kit WordPress plugin versions prior to 1.5.7. The vulnerability arises because the plugin does not properly sanitize and escape a parameter before including it in a SQL query. On multisite WordPress installations, this enables an administrator of a single site to execute SQL injection attacks that can read data belonging to the entire network, which would normally be inaccessible to them.
Potential Impact
An attacker with administrator privileges on a single site within a multisite WordPress network can exploit this vulnerability to perform SQL injection attacks. This can lead to unauthorized disclosure of data across the entire multisite network, violating data confidentiality boundaries between sites.
Mitigation Recommendations
No official patch or remediation guidance is currently available. Users should monitor the vendor's advisory for updates and apply version 1.5.7 or later once released, as this version is indicated as fixed. Until then, restrict administrator privileges carefully and consider disabling the plugin on multisite installations if feasible.
