Unauthenticated SQL Injection in WordPress Radio Schedule Plugin

The Tz Weekly Radio Schedule WordPress plugin through 1.8.1 does not sanitize and escape a parameter before using it to build a SQL query on an AJAX action 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

The Tz Weekly Radio Schedule WordPress plugin versions through 1.8.1 contain a critical SQL injection vulnerability in an AJAX action accessible to unauthenticated users. By failing to sanitize and escape user-supplied parameters before incorporating them into SQL queries, attackers can inject arbitrary SQL commands to manipulate database queries, extract sensitive data, and potentially compromise the entire WordPress installation. This vulnerability is particularly dangerous because it requires no authentication, meaning any visitor to a site running the vulnerable plugin can exploit it. Organizations using this plugin face immediate risk of data exfiltration, including user credentials, configuration details, and other sensitive information stored in the WordPress database.

Casky's 323 matched security skills leverage Claude AI's extended reasoning to detect the attack patterns associated with this vulnerability across MITRE ATT&CK techniques TA0001 (Reconnaissance) and TA0043 (Reconnaissance). Practitioners using Casky would identify suspicious AJAX requests with malformed parameters, detect unusual SQL query patterns in application logs, and spot database error messages that reveal schema information—all hallmarks of SQL injection reconnaissance and exploitation attempts. The platform's skill mapping enables detection of attackers probing for injectable parameters, analyzing database responses for information disclosure, and monitoring for data exfiltration activities that follow successful injection attacks. By correlating these behavioral indicators with known exploitation patterns, security teams can rapidly identify compromise attempts before sensitive data is extracted.
