CVE-2025-67987 identifies an SQL Injection vulnerability in the ExpressTech Systems Quiz And Survey Master WordPress plugin, versions up to and including 10.3.1. The vulnerability stems from improper neutralization of special characters in SQL commands, which allows an attacker with authenticated access and low privileges to inject arbitrary SQL code. This can lead to unauthorized disclosure of sensitive data stored in the backend database, such as user information, survey results, or configuration details. The vulnerability does not require user interaction but does require the attacker to be authenticated, which limits exploitation scope but still poses a serious risk in multi-user environments. The CVSS 3.1 vector (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:L) reflects network exploitability with low attack complexity, requiring privileges but no user interaction, and a high impact on confidentiality with limited impact on integrity and availability. Although no known exploits are currently reported in the wild, the widespread use of this plugin in educational, corporate, and research environments increases the potential attack surface. The vulnerability highlights the need for secure coding practices in handling SQL queries and input validation within WordPress plugins.

The primary impact of CVE-2025-67987 is the potential unauthorized disclosure of sensitive data stored in the database, which can include personally identifiable information, survey responses, and internal configurations. This breach of confidentiality can lead to privacy violations, regulatory non-compliance, and reputational damage. Since the vulnerability requires authenticated access, insider threats or compromised user accounts pose a significant risk. The limited impact on integrity and availability reduces the risk of data manipulation or service disruption, but the confidentiality breach alone is critical. Organizations relying on Quiz And Survey Master for data collection and analysis could face data leaks that undermine trust and expose them to legal liabilities. The vulnerability's network accessibility and low complexity of exploitation mean attackers can leverage it remotely once authenticated, increasing the urgency for mitigation.

To mitigate CVE-2025-67987, organizations should first restrict access to the Quiz And Survey Master plugin by limiting user roles and permissions to only trusted users. Implement strict authentication and monitoring to detect suspicious activities involving the plugin. Employ web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting this plugin. Regularly audit database queries and logs for anomalous patterns indicative of injection attempts. Since no official patch links are currently available, monitor ExpressTech Systems' advisories for updates and apply patches promptly once released. Additionally, consider isolating the database user account used by the plugin with minimal privileges to limit data exposure in case of exploitation. Educate administrators and users about the risks of SQL injection and enforce secure coding practices for any customizations involving database interactions.
