CVE-2024-23507 is a high-severity SQL Injection vulnerability (CWE-89) affecting the InstaWP Connect – 1-click WP Staging & Migration plugin developed by InstaWP Team. This plugin is used to facilitate WordPress site staging and migration with a single click. The vulnerability arises from improper neutralization of special elements in SQL commands, allowing an authenticated attacker with low privileges (PR:L) to inject malicious SQL code remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts all versions up to 0.1.0.9. Exploitation can lead to unauthorized disclosure of sensitive data (confidentiality impact is high), though it does not directly affect data integrity but may cause limited availability impact. The scope is changed (S:C), meaning the vulnerability can affect resources beyond the initially compromised component. The lack of known exploits in the wild suggests it is newly disclosed, but the high CVSS score (8.5) indicates significant risk if exploited. The plugin’s role in WordPress staging and migration means it interacts with database operations, making SQL injection particularly dangerous as it can expose or manipulate backend data. Since the vulnerability requires authentication but only low privileges, attackers who have compromised or gained low-level access to a WordPress environment could leverage this flaw to escalate data exposure. No patches or mitigation links are currently provided, emphasizing the need for immediate attention from users of this plugin.

For European organizations, the impact of this vulnerability could be substantial, especially for businesses relying on WordPress for their web presence and using InstaWP Connect for staging or migration. Exploitation could lead to unauthorized access to sensitive customer data, internal business information, or intellectual property stored in the WordPress database. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and potential financial penalties. The ability to perform SQL injection remotely with low privileges increases the attack surface, particularly for organizations with multiple users having low-level access to WordPress admin or staging environments. Additionally, the staging and migration context means that compromised data could propagate to production or backup environments, amplifying the risk. The limited availability impact could disrupt website functionality or staging operations, affecting business continuity and development workflows. Given the widespread use of WordPress across European SMEs and enterprises, the vulnerability presents a credible threat vector that must be addressed promptly.

1. Immediate action should include disabling or uninstalling the InstaWP Connect plugin until a security patch is released. 2. Restrict access to WordPress admin and staging environments to trusted users only, enforcing strong authentication and role-based access controls to minimize the risk of low-privilege account compromise. 3. Monitor WordPress logs and database query logs for unusual or suspicious activity indicative of SQL injection attempts. 4. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the plugin’s endpoints. 5. Regularly update all WordPress plugins and core installations to the latest versions once patches become available. 6. Conduct security audits and penetration testing focused on staging and migration workflows to identify and remediate similar vulnerabilities. 7. Backup WordPress databases and site files frequently and verify the integrity of backups to enable recovery in case of compromise. 8. Educate WordPress administrators and developers about secure coding practices and the risks of SQL injection, emphasizing the importance of input validation and parameterized queries.
