CVE-2025-10187 identifies an SQL Injection vulnerability in the GSpeech TTS – WordPress Text To Speech Plugin, affecting all versions up to and including 3.17.13. The vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89), specifically due to insufficient escaping of the 'field' parameter supplied by users and lack of prepared statements or parameterized queries in the plugin's code. This flaw allows an attacker with authenticated Administrator-level access to append arbitrary SQL queries to existing ones, enabling unauthorized extraction of sensitive information from the WordPress database. The attack vector is network-based, requiring no user interaction but high privileges, limiting exploitation to trusted users with admin rights. The vulnerability impacts confidentiality but does not affect data integrity or availability. Although no known exploits are currently reported in the wild, the medium CVSS score of 4.9 reflects the moderate risk due to the required privilege level. The plugin is widely used in WordPress environments for text-to-speech functionality, making this vulnerability relevant for websites relying on this plugin for accessibility or content delivery. The absence of patches at the time of reporting necessitates immediate mitigation steps to prevent potential data leakage.

For European organizations, this vulnerability poses a significant risk to the confidentiality of sensitive data stored within WordPress databases, including user information, content, and potentially business-critical data. Since exploitation requires Administrator-level access, the threat is primarily from insider threats or compromised admin accounts. Successful exploitation could lead to unauthorized data disclosure, undermining privacy compliance obligations such as GDPR. Although the vulnerability does not directly affect data integrity or availability, the exposure of sensitive information could lead to reputational damage, regulatory penalties, and loss of customer trust. Organizations running WordPress sites with the GSpeech TTS plugin, especially those handling personal or financial data, are at heightened risk. The medium severity rating suggests that while the threat is not critical, it should be addressed promptly to avoid escalation or chaining with other vulnerabilities.

1. Immediately restrict Administrator-level access to trusted personnel and enforce strong authentication mechanisms, such as multi-factor authentication (MFA), to reduce the risk of credential compromise. 2. Monitor and audit admin account activities for unusual behavior that could indicate exploitation attempts. 3. Implement Web Application Firewalls (WAF) with custom rules designed to detect and block SQL Injection attempts targeting the 'field' parameter in the GSpeech TTS plugin. 4. Regularly update WordPress core and plugins; monitor the vendor's announcements for patches addressing this vulnerability and apply them promptly once available. 5. Employ database activity monitoring tools to detect anomalous queries indicative of injection attacks. 6. Consider isolating WordPress instances with this plugin in segmented network zones to limit lateral movement in case of compromise. 7. Educate administrators on the risks of SQL Injection and the importance of secure plugin management. 8. As a temporary workaround, if feasible, disable or remove the GSpeech TTS plugin until a secure version is released.
