Unauthenticated SQL Injection in WordPress Q&A Plugin

The Product Question and Answer WordPress plugin through 1.1.0 does not sanitize and escape parameters before using them in SQL queries on AJAX actions available to unauthenticated users, allowing unauthenticated attackers to perform SQL injection attacks and extract sensitive data from the database.

Casky was already ahead

This CVE exploits attack patterns that Casky's 323matched 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

This vulnerability represents a critical authentication bypass combined with SQL injection in the Product Question and Answer WordPress plugin versions up to 1.1.0. The flaw allows unauthenticated attackers to inject malicious SQL code through unsanitized AJAX parameters, potentially exposing entire databases containing user credentials, personal information, and business data. Any WordPress site running this plugin is immediately vulnerable without requiring user authentication, making this a high-risk threat to thousands of websites relying on this functionality for customer engagement.

Casky's 323 mapped skills enable practitioners to identify this attack pattern by correlating MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance)—specifically through detection of suspicious SQL query patterns, unusual AJAX endpoint access from non-authenticated sources, and database query anomalies. When Claude AI analyzes network traffic and application logs, practitioners would see flagged indicators such as SQL metacharacters in HTTP parameters, unexpected database permission requests, and data exfiltration attempts targeting wp_users or wp_postmeta tables. The extended reasoning capability allows security teams to distinguish legitimate question submissions from reconnaissance probes attempting to enumerate database structure, enabling faster incident response and vulnerability remediation.
