CVE-2026-2429 in Community Events Plugin
Summary
by MITRE • 03/07/2026
The Community Events plugin for WordPress is vulnerable to SQL Injection via the 'ce_venue_name' CSV field in the `on_save_changes_venues` function in all versions up to, and including, 1.5.8. This is due to insufficient escaping on the user-supplied CSV data and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database via a crafted CSV file upload.

The vulnerability identified as CVE-2026-2429 affects the Community Events plugin for WordPress, specifically targeting versions up to and including 1.5.8. This represents a critical security flaw that exploits a SQL injection vulnerability within the plugin's data handling mechanisms. The issue manifests through the 'ce_venue_name' CSV field in the `on_save_changes_venues` function, where the plugin fails to properly sanitize user-supplied data before incorporating it into database queries. This vulnerability falls under the CWE-89 category, which specifically addresses SQL injection flaws, and aligns with ATT&CK technique T1071.004 for application layer protocol manipulation. The vulnerability is particularly concerning because it requires only authenticated access with administrator-level privileges, making it accessible to users who already have significant control over the WordPress installation.
The technical implementation of this vulnerability stems from inadequate input validation and sanitization practices within the plugin's CSV import functionality. When administrators upload CSV files containing venue information, the plugin processes the 'ce_venue_name' field without proper escaping or parameterization of the data. This allows malicious actors to inject additional SQL commands that become part of the existing database query structure. The flaw exists because the plugin does not employ prepared statements or proper escaping mechanisms for the user-provided data, creating an environment where crafted CSV uploads can manipulate the underlying database operations. The vulnerability specifically targets the on_save_changes_venues function, which serves as the entry point for processing venue data during CSV import operations, making it a direct pathway for database manipulation.
The operational impact of this vulnerability extends beyond simple data extraction, as it provides authenticated attackers with the capability to perform arbitrary database operations. An attacker with administrator access can construct malicious CSV files that, when processed by the vulnerable plugin, execute additional SQL queries designed to extract sensitive information from the database. This could include user credentials, personal information, plugin configurations, or other confidential data stored within the WordPress database. The vulnerability's exploitation requires minimal technical expertise beyond understanding CSV file structures and basic SQL injection techniques, making it particularly dangerous in environments where administrative privileges are compromised. The attack vector is specifically designed around CSV file uploads, which are commonly used for bulk data operations in content management systems, increasing the likelihood of successful exploitation in real-world scenarios.
Mitigation strategies for CVE-2026-2429 should prioritize immediate plugin updates to versions that address the SQL injection vulnerability, as this represents the most effective solution. Organizations should also implement network-level restrictions to limit access to the CSV import functionality and monitor for suspicious file uploads. Additional protective measures include implementing proper input validation and sanitization for all user-supplied data, particularly in file upload handlers, and ensuring that all database queries utilize prepared statements with proper parameter binding. Security teams should conduct thorough audits of plugin code to identify similar vulnerabilities and establish robust access controls for administrative functions. The vulnerability highlights the importance of following secure coding practices such as those outlined in the OWASP Top Ten and emphasizes the need for regular security assessments of third-party plugins in WordPress environments. Organizations should also consider implementing automated scanning tools to detect and prevent the execution of malicious CSV files, while maintaining detailed logging of all database operations to facilitate incident response activities.
