CVE-2026-9700 in Eventer Plugin
Summary
by MITRE • 07/08/2026
The Eventer plugin for WordPress is vulnerable to time-based SQL Injection via the ‘code’ parameter in all versions up to, and including, 4.4.2 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.

The Eventer plugin for WordPress represents a significant security vulnerability through its susceptibility to time-based SQL injection attacks, specifically targeting the 'code' parameter within versions up to and including 4.4.2. This flaw stems from inadequate input sanitization practices where user-supplied data fails to undergo proper escaping before being incorporated into database queries. The vulnerability exists because the plugin does not employ sufficient prepared statement mechanisms or parameterized queries to separate executable code from data inputs, creating an environment where malicious actors can manipulate database operations through crafted payloads.
The technical implementation of this vulnerability allows unauthenticated attackers to exploit the insufficient escaping mechanism by injecting time-based SQL commands that cause the database server to delay responses based on boolean conditions. When the 'code' parameter receives malicious input, the plugin processes this data without proper validation or sanitization, enabling attackers to construct queries that can extract sensitive information from the underlying database through timing variations in response times. This methodology relies on the database's ability to introduce deliberate delays when certain conditions are met, allowing attackers to infer information about the database structure and contents through a process of trial and error.
The operational impact of this vulnerability extends beyond simple data theft, as it provides attackers with the capability to perform extensive reconnaissance operations against WordPress installations using the Eventer plugin. Unauthenticated threat actors can leverage this weakness to extract user credentials, administrative information, configuration details, and other sensitive data stored within the database without requiring prior authorization or access privileges. The vulnerability affects all versions up to 4.4.2, indicating a prolonged period during which the security flaw remained unaddressed, potentially exposing numerous websites to exploitation.
Security professionals should note that this vulnerability aligns with common weakness enumerations such as CWE-89 SQL Injection and CWE-77 SQL Injection, while also mapping to attack techniques documented in the MITRE ATT&CK framework under T1213 Data from Information Repositories. The lack of proper input validation and insufficient query preparation directly violates fundamental security practices recommended by OWASP and other industry standards for preventing database-related vulnerabilities. Organizations should immediately implement patch management procedures to upgrade to versions that address this vulnerability, while also considering network-level mitigations such as web application firewalls and intrusion detection systems to monitor for exploitation attempts.
The remediation strategy requires immediate deployment of the latest plugin version that contains proper input sanitization and parameterized query implementations. Security teams must also conduct thorough vulnerability assessments across their WordPress environments to identify any other instances where similar input handling practices might exist, particularly in custom plugins or themes that may exhibit analogous weaknesses. Additionally, implementing proper logging mechanisms and monitoring for unusual database access patterns can help detect potential exploitation attempts and provide early warning capabilities against similar vulnerabilities in the future.
