CVE-2025-10187 in GSpeech TTS Plugin
Summary
by MITRE • 10/18/2025
The GSpeech TTS – WordPress Text To Speech Plugin plugin for WordPress is vulnerable to SQL Injection via the 'field' parameter in all versions up to, and including, 3.17.13 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.

The CVE-2025-10187 vulnerability affects the GSpeech TTS WordPress plugin, specifically targeting versions up to and including 3.17.13. This security flaw represents a critical SQL injection vulnerability that exploits improper input validation within the plugin's handling of the 'field' parameter. The vulnerability exists due to inadequate escaping of user-supplied parameters and insufficient preparation of existing SQL queries, creating a dangerous attack vector that can be exploited by authenticated attackers with administrator-level privileges or higher.
The technical implementation of this vulnerability stems from the plugin's failure to properly sanitize input data before incorporating it into database queries. When an authenticated attacker with administrative access submits malicious input through the 'field' parameter, the plugin processes this data without adequate protection mechanisms. This allows the attacker to inject additional SQL commands that become part of the existing database query structure. The vulnerability maps directly to CWE-89, which specifically addresses SQL injection flaws where insufficient input validation permits malicious SQL code execution. The attack chain typically involves crafting malicious payloads that exploit the parameter handling to manipulate the underlying SQL statement structure.
The operational impact of this vulnerability is severe and far-reaching for affected WordPress installations. An attacker with administrator-level access can leverage this vulnerability to extract sensitive information from the database including user credentials, configuration settings, and other confidential data. The vulnerability enables attackers to perform unauthorized data access and potentially escalate their privileges further within the compromised system. This represents a significant threat to WordPress site security as it allows for persistent access to critical system information and could facilitate additional attacks such as data exfiltration or system compromise. The vulnerability's classification aligns with ATT&CK technique T1078 which covers valid accounts and credential access, as it exploits legitimate administrative privileges to gain deeper system access.
Mitigation strategies for CVE-2025-10187 require immediate action from system administrators. The primary recommendation is to upgrade the GSpeech TTS plugin to the latest available version that contains proper input sanitization and SQL query preparation mechanisms. Organizations should also implement network segmentation and access controls to limit administrative access to only necessary personnel. Additional protective measures include monitoring database query logs for suspicious activity and implementing web application firewalls that can detect and block SQL injection attempts. Regular security audits and vulnerability assessments should be conducted to identify similar issues in other plugins and themes. The remediation process should also involve reviewing and strengthening authentication mechanisms to ensure that only authorized users can access administrative functions. System administrators should also consider implementing database query parameterization and input validation at multiple layers to provide defense-in-depth protection against similar vulnerabilities.
