CVE-2025-7036 in CleverReach WP Plugin
Summary
by MITRE • 08/06/2025
The CleverReach® WP plugin for WordPress is vulnerable to time-based SQL Injection via the ‘title’ parameter in all versions up to, and including, 1.5.20 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 CleverReach® WP plugin for WordPress represents a widely used marketing automation tool that integrates with wordpress platforms to manage email campaigns and subscriber data. This particular vulnerability affects all versions up to and including 1.5.20, making it a significant concern for wordpress administrators who rely on this plugin for their email marketing operations. The plugin's architecture processes user-supplied data through the 'title' parameter without adequate sanitization measures, creating an exploitable entry point for malicious actors seeking to compromise wordpress installations.
The technical flaw manifests as a time-based sql injection vulnerability that occurs when the plugin fails to properly escape the 'title' parameter before incorporating it into database queries. This insufficient escaping allows attackers to manipulate the sql query structure by appending additional sql commands that can be executed within the existing database context. The vulnerability operates through timing mechanisms where the attacker can infer information from the database based on response delays, making it particularly dangerous as it can be exploited without authentication requirements. The lack of proper sql query preparation means that user input directly influences the query execution flow, creating a direct path for malicious sql commands to be interpreted and executed by the database engine.
The operational impact of this vulnerability extends beyond simple data theft, as unauthenticated attackers can potentially extract sensitive information from wordpress databases including user credentials, subscriber lists, campaign data, and other confidential information stored within the integrated CleverReach system. This vulnerability particularly affects wordpress installations where the CleverReach plugin is actively used, potentially compromising entire wordpress environments if the database contains additional sensitive information beyond just the plugin data. The time-based nature of the injection means that attackers can systematically extract data through multiple query attempts, making the exploitation process both efficient and stealthy.
Security professionals should immediately implement mitigation strategies including updating to the latest plugin version where this vulnerability has been addressed, implementing web application firewalls to detect and block suspicious sql injection patterns, and conducting thorough security audits of wordpress installations to identify any potential exploitation attempts. Organizations should also consider implementing database query logging and monitoring to detect anomalous sql execution patterns that may indicate exploitation attempts. The vulnerability aligns with CWE-89 which specifically addresses sql injection flaws, and represents a clear violation of secure coding practices that should be addressed through proper input validation and parameterized queries. From an att&ck perspective, this vulnerability maps to technique T1190 - exploit public-facing application, highlighting the need for proper input sanitization and the importance of keeping all wordpress plugins updated to prevent exploitation through publicly accessible interfaces.
