CVE-2025-49059 is a critical SQL Injection vulnerability affecting the CleverReach® WP plugin, a WordPress integration tool used for email marketing and campaign management. The vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89), allowing an unauthenticated attacker to inject malicious SQL code remotely (AV:N/AC:L/PR:N/UI:N). The CVSS 3.1 score of 9.3 reflects the high severity and ease of exploitation without any privileges or user interaction. The vulnerability impacts all versions of CleverReach® WP up to 1.5.20. Exploitation could allow attackers to extract sensitive data from the backend database, such as user credentials, campaign data, or other confidential information, compromising confidentiality. Although the integrity impact is rated as none in the CVSS vector, attackers could potentially manipulate queries to disrupt data or cause limited availability issues (rated low availability impact). The scope is changed (S:C), indicating that exploitation could affect resources beyond the vulnerable component, potentially impacting the entire WordPress site and its data. No known exploits have been reported in the wild yet, and no patches are currently available, increasing the urgency for organizations to monitor for updates and apply mitigations. Given the widespread use of WordPress and the popularity of CleverReach® WP in managing marketing campaigns, this vulnerability poses a significant risk to organizations relying on this plugin for their digital communications.

For European organizations, the impact of this vulnerability is substantial due to the potential exposure of sensitive customer data, marketing strategies, and internal communications stored within the CleverReach® WP plugin database. Data breaches resulting from SQL Injection can lead to violations of GDPR and other data protection regulations, resulting in legal penalties and reputational damage. The ability to extract confidential information without authentication increases the risk of targeted attacks, including phishing campaigns leveraging stolen data. Additionally, the compromise of marketing infrastructure could disrupt business operations and customer engagement. Organizations in sectors such as retail, finance, and healthcare that rely heavily on email marketing and customer data management are particularly vulnerable. The changed scope of the vulnerability means that exploitation could affect the entire WordPress environment, potentially leading to broader system compromises. The lack of available patches and known exploits in the wild necessitates immediate attention to prevent exploitation.

European organizations should take immediate and specific actions to mitigate this vulnerability beyond generic advice. First, they should conduct an inventory to identify all WordPress instances using the CleverReach® WP plugin and determine the versions deployed. Until an official patch is released, organizations should consider temporarily disabling the CleverReach® WP plugin to eliminate the attack surface. Implementing Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection patterns targeting CleverReach® WP endpoints can provide interim protection. Organizations should also enable detailed logging and monitoring of database queries and web application traffic to detect suspicious activity indicative of exploitation attempts. Regular backups of WordPress sites and databases should be maintained to enable rapid recovery in case of compromise. Additionally, organizations should subscribe to vendor and security advisories to promptly apply patches once available. Conducting internal security assessments and penetration tests focusing on SQL Injection vulnerabilities in WordPress plugins can help identify other potential weaknesses. Finally, educating IT and security teams about this specific threat will improve incident response readiness.
