CVE-2025-10187 is an SQL Injection vulnerability identified in the GSpeech TTS – WordPress Text To Speech Plugin, affecting all versions up to and including 3.17.13. The root cause is insufficient escaping and lack of proper preparation of the 'field' parameter in SQL queries, which allows authenticated users with administrator privileges to append arbitrary SQL commands to existing queries. This vulnerability falls under CWE-89, indicating improper neutralization of special elements in SQL commands. The attack vector is network-based, requiring low attack complexity but high privileges (administrator access) and no user interaction. Successful exploitation can lead to unauthorized disclosure of sensitive information stored in the WordPress database, such as user data, configuration details, or other confidential content. The CVSS v3.1 score is 4.9 (medium severity), reflecting the high confidentiality impact but no impact on integrity or availability. No public exploits are currently known, but the vulnerability poses a risk to websites using this plugin, especially those with multiple administrators or weak access controls. The lack of a patch link suggests that a fix may not yet be available, emphasizing the need for immediate mitigation steps.

The primary impact of this vulnerability is unauthorized disclosure of sensitive data from the WordPress database. Attackers with administrator privileges can leverage the SQL Injection flaw to extract confidential information, potentially including user credentials, personal data, or site configuration details. Although the vulnerability does not allow modification or deletion of data (integrity impact is none) or denial of service (availability impact is none), the exposure of sensitive information can lead to further attacks, such as credential theft, privilege escalation, or targeted phishing. Organizations running websites with this plugin are at risk of data breaches, reputational damage, and compliance violations, especially if sensitive customer or business data is exposed. The requirement for administrator-level access limits the attack surface but does not eliminate risk, as compromised or malicious administrators can exploit this vulnerability. The absence of known exploits reduces immediate risk but does not preclude future exploitation.

1. Immediately restrict administrator access to trusted personnel only and enforce strong authentication mechanisms such as multi-factor authentication (MFA) to reduce the risk of compromised admin accounts. 2. Monitor database query logs for unusual or unexpected SQL commands that may indicate exploitation attempts. 3. If possible, disable or uninstall the GSpeech TTS plugin until a security patch is released. 4. Apply principle of least privilege by limiting plugin usage and administrative rights on WordPress installations. 5. Implement Web Application Firewall (WAF) rules to detect and block SQL Injection patterns targeting the 'field' parameter in plugin requests. 6. Regularly update WordPress core, plugins, and themes to incorporate security patches once available. 7. Conduct code review and testing to ensure proper input validation and parameterized queries are used in plugin code. 8. Backup website and database regularly to enable recovery in case of compromise. 9. Educate administrators about the risks of SQL Injection and the importance of secure plugin management.
