CVE-2025-7402 is a time-based SQL Injection vulnerability identified in the Ads Pro Plugin - Multi-Purpose WordPress Advertising Manager, a widely used WordPress plugin for managing advertisements. The vulnerability exists in all versions up to and including 4.95 due to improper neutralization of special elements in the 'site_id' parameter. Specifically, the plugin fails to adequately escape user-supplied input and does not use prepared statements or parameterized queries, allowing attackers to append malicious SQL commands to legitimate queries. This flaw enables unauthenticated attackers to perform time-based blind SQL Injection attacks, which can be used to infer and extract sensitive information from the backend database, such as user credentials, configuration data, or advertising metrics. The attack vector requires no authentication or user interaction, increasing the risk of automated exploitation. Although no public exploits have been reported yet, the vulnerability's CVSS score of 7.5 reflects its high impact on confidentiality and ease of exploitation. The plugin's widespread use in WordPress sites, especially those managing advertising content, makes this vulnerability a critical concern for website owners and administrators. The absence of available patches at the time of disclosure necessitates immediate attention to alternative mitigation strategies.

The primary impact of CVE-2025-7402 is the compromise of data confidentiality through unauthorized extraction of sensitive information from the database. For European organizations, this could lead to exposure of customer data, advertising strategies, financial information, or internal configurations, potentially resulting in reputational damage, regulatory penalties under GDPR, and financial losses. Since the vulnerability does not affect integrity or availability directly, the main concern remains data leakage. However, attackers could leverage extracted data for further attacks, including privilege escalation or lateral movement. The fact that exploitation requires no authentication and no user interaction increases the likelihood of automated scanning and exploitation attempts. Organizations relying on the Ads Pro Plugin for critical advertising revenue streams or customer engagement may face operational disruptions if data breaches occur. Additionally, regulatory compliance frameworks in Europe impose strict requirements on protecting personal data, making this vulnerability particularly consequential for affected entities.

1. Immediate monitoring for updates from the plugin vendor and prompt application of patches once released is critical. 2. Until patches are available, deploy a Web Application Firewall (WAF) with custom rules to detect and block SQL Injection attempts targeting the 'site_id' parameter. 3. Implement strict input validation and sanitization on all user-supplied parameters at the application or server level to prevent malicious payloads. 4. Restrict database user permissions to the minimum necessary, avoiding excessive privileges that could be exploited if injection occurs. 5. Conduct regular security audits and vulnerability scans focusing on WordPress plugins, especially those handling user input and database interactions. 6. Consider isolating or disabling the vulnerable plugin if it is not essential or replacing it with a more secure alternative. 7. Enhance logging and monitoring to detect unusual query patterns or access attempts indicative of exploitation. 8. Educate site administrators about the risks and signs of SQL Injection attacks to improve incident response readiness.
