SQL Injection in WordPress Page Duplicator Plugin

The sm page duplicator WordPress plugin through 1.0.0 does not sanitise and escape a stored value before using it in a SQL statement when duplicating a page, allowing users with the Editor role and above to perform SQL Injection attacks.

Casky was already ahead

This CVE exploits attack patterns that Casky's 322matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.

Analysis

The SM Page Duplicator WordPress plugin through version 1.0.0 contains a critical SQL injection vulnerability (CWE-89) in its page duplication functionality. The plugin fails to properly sanitize and escape user-supplied input before incorporating it into SQL queries, enabling authenticated users with Editor role or higher privileges to execute arbitrary SQL commands. This vulnerability matters because WordPress sites rely on role-based access controls to prevent data breaches—attackers with Editor access could extract sensitive database information, modify content, or escalate privileges. Any organization running this plugin version is at risk, particularly those with multiple editors or contributors who may be compromised accounts.

Casky's 322 mapped security skills leverage Claude AI's extended reasoning to detect the attack patterns associated with this vulnerability across two critical MITRE ATT&CK techniques: TA0001 (Initial Access/Reconnaissance) and TA0043 (Reconnaissance). Practitioners using Casky would identify suspicious patterns including unsanitized parameter handling in page duplication requests, SQL error messages revealing database structure, and unusual database query patterns in access logs. The platform's skills would flag instances where user input flows directly into SQL statements without parameterized queries or prepared statements, detecting both the code-level vulnerability and post-exploitation indicators like unauthorized data exfiltration or schema enumeration attempts. This enables defenders to pinpoint vulnerable installations and detect active exploitation before significant damage occurs.
