CVE-2025-4381 is a high-severity SQL Injection vulnerability affecting the Ads Pro Plugin - Multi-Purpose WordPress Advertising Manager developed by scripteo. This vulnerability exists in all versions up to and including 4.89 of the plugin. The root cause is improper neutralization of special elements in SQL commands, specifically due to insufficient escaping and lack of parameterized queries in the getSpace() function's handling of the '$id' variable. An unauthenticated attacker can exploit this flaw by injecting malicious SQL code into the '$id' parameter, which is directly incorporated into SQL queries without proper sanitization or use of prepared statements. This allows the attacker to append additional SQL commands, potentially extracting sensitive information from the underlying database. The vulnerability does not require any user authentication or interaction, making it remotely exploitable over the network. The CVSS v3.1 base score is 7.5 (High), reflecting the ease of exploitation (network vector, no privileges, no user interaction) and the high impact on confidentiality due to data disclosure. The integrity and availability impacts are rated as none, indicating the attack primarily leaks data without modifying or disrupting service. No known exploits are currently reported in the wild, but the vulnerability's nature and accessibility make it a significant risk for WordPress sites using this plugin. The lack of available patches at the time of publication further increases exposure risk. This vulnerability falls under CWE-89, which is a common and well-understood category of injection flaws that have historically led to severe data breaches and compromise of web applications. Organizations using this plugin should prioritize remediation to prevent unauthorized data access and potential follow-on attacks leveraging exposed information.

For European organizations, this vulnerability poses a substantial risk, especially for those relying on WordPress websites with the Ads Pro Plugin installed for advertising management. Exploitation can lead to unauthorized disclosure of sensitive data stored in the database, including potentially personal data protected under GDPR. This could result in regulatory penalties, reputational damage, and loss of customer trust. The vulnerability's unauthenticated remote exploitability means attackers can target websites indiscriminately, increasing the likelihood of automated scanning and exploitation campaigns. Given the widespread use of WordPress across Europe and the popularity of advertising plugins, many SMEs and larger enterprises could be affected. Additionally, organizations in sectors with high-value data such as finance, healthcare, and e-commerce are at greater risk due to the sensitivity of their stored information. The exposure of confidential data could facilitate further attacks such as phishing, identity theft, or lateral movement within compromised networks. Moreover, the lack of integrity and availability impact reduces the risk of service disruption but does not diminish the severity of data confidentiality breaches. European entities must consider the compliance implications under GDPR, which mandates prompt breach notification and adequate security measures to protect personal data.

To mitigate this vulnerability, European organizations should immediately audit their WordPress installations to identify the presence of the Ads Pro Plugin and verify the version in use. Since no official patches are available at the time of reporting, temporary mitigations include disabling or uninstalling the plugin to eliminate the attack surface. If the plugin is essential, organizations should implement Web Application Firewall (WAF) rules specifically designed to detect and block SQL injection attempts targeting the '$id' parameter in the getSpace() function. Custom WAF signatures can be created to filter out suspicious input patterns such as SQL control characters and keywords. Additionally, organizations should monitor web server logs for anomalous query strings or repeated failed attempts indicative of exploitation attempts. It is also advisable to restrict database user permissions associated with the WordPress application to the minimum required, preventing excessive data exposure if exploited. Once a patch or updated plugin version is released by the vendor, prompt application of the update is critical. Organizations should also conduct security awareness training for administrators to recognize and respond to potential exploitation signs. Regular backups of website data and databases should be maintained to ensure recovery capability in case of compromise. Finally, implementing a comprehensive vulnerability management program that includes timely scanning for known vulnerabilities in third-party plugins will help prevent similar risks in the future.
