Unauthenticated SQL Injection in Modern Event Calendar WordPress

The Modern Event Calendar Pro WordPress plugin before 7.34.0, Modern Events Calendar Lite WordPress plugin before 7.34.0 do not sanitise and escape a request parameter before using it in a SQL statement, through an AJAX action available to unauthenticated users, leading to an unauthenticated SQL injection vulnerability that allows attackers to extract sensitive data from the database.

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

Modern Event Calendar Pro and Lite WordPress plugins before version 7.34.0 contain a critical unauthenticated SQL injection vulnerability (CWE-89) in an AJAX action endpoint. The vulnerability stems from insufficient input sanitization and output escaping of request parameters before they are incorporated into SQL statements. Because the vulnerable AJAX action is accessible to unauthenticated users, attackers can exploit this without requiring WordPress credentials. This directly impacts any WordPress installation running the affected plugin versions, potentially exposing sensitive database contents including user credentials, customer data, and configuration information. The high CVSS score of 8.6 reflects the combination of network accessibility, low attack complexity, and significant impact on confidentiality.

Casky's 322 matching skills leverage Claude AI's extended reasoning to detect the attack patterns underlying this vulnerability across two critical MITRE ATT&CK techniques: TA0001 (Initial Access) and TA0043 (Reconnaissance). Practitioners using Casky would identify suspicious patterns including unauthenticated AJAX requests with SQL metacharacters or union-based injection payloads targeting the vulnerable endpoint, unusual database query patterns in logs, and reconnaissance activities probing for plugin version information. The platform's skill mapping helps teams correlate injection attempts with subsequent data exfiltration, enabling detection of the complete attack chain from reconnaissance through data extraction. By analyzing request parameters, SQL error messages, and anomalous database access patterns, Casky helps practitioners distinguish legitimate traffic from exploitation attempts and prioritize remediation efforts.
