Overview
A critical security flaw, identified as CVE-2025-10042, has been discovered in the popular Quiz Maker plugin for WordPress. This vulnerability is a type of SQL Injection, a serious issue that could allow malicious actors to steal sensitive information directly from your website’s database. This particular flaw affects all versions of the Quiz Maker plugin up to, and including, 6.7.0.56. Exploiting this vulnerability depends on specific server settings: your server must be configured to retrieve a user’s IP address from a spoofable header, like X-Forwarded-For, and also have IP-based user limits enabled. Under these conditions, an unauthenticated attacker could craft special requests to manipulate existing SQL queries, potentially exposing private data.
CVE Details
- Product: Quiz Maker plugin for WordPress
- Published Date: September 17, 2025
- Severity: Medium
- Status: Analyzed
Affected Products
The SQL Injection vulnerability (CVE-2025-10042) impacts the Quiz Maker plugin for WordPress. Specifically, all versions up to, and including, 6.7.0.56 are affected. If you are running any version within this range, and your server meets the specific configuration requirements, your website could be at risk.
Current Status
This vulnerability has been thoroughly analyzed and publicly disclosed. Cybersecurity researchers have detailed the technical aspects, and a fix has been released by the plugin developers. This allows web administrators and developers to take necessary actions to protect their websites by updating to a patched version, ensuring their systems are no longer vulnerable.
Severity Level
The severity for CVE-2025-10042 is rated as Medium, with a CVSS score of 5.9. A medium rating signifies that while the vulnerability carries a notable risk, its exploitability might be constrained by specific prerequisites or demand a certain level of skill from an attacker. In this particular instance, the requirement for a specific server configuration—where the IP is sourced from X-Forwarded-For and IP-based user limits are active—naturally limits the immediate threat surface. Nevertheless, it remains a serious concern for administrators of affected systems, as successful exploitation could lead to unauthorized data disclosure, impacting user privacy and site integrity.
Possible Solutions
The most critical and immediate action you can take to safeguard your WordPress site from CVE-2025-10042 is to update the Quiz Maker plugin without delay. The developers have promptly released a patched version designed to eliminate this SQL Injection vulnerability.
- Update Your Plugin: It is imperative to update your Quiz Maker plugin to version 6.7.0.57 or newer. This updated version incorporates the necessary security fixes to prevent the exploitation of this flaw. Always ensure you back up your site before performing any updates.
- Scrutinize Server Configuration: If your website operates behind reverse proxies, CDNs, or load balancers, it’s crucial to review how your server determines a user’s IP address. Ensure that any mechanisms relying on headers like
X-Forwarded-Forare implemented with robust validation to prevent IP spoofing. - Evaluate IP-Based Limits: If your use of IP-based user limits within the Quiz Maker plugin or your server setup is not strictly essential, consider temporarily or permanently disabling this feature. Removing this condition significantly reduces the window for this specific vulnerability to be exploited.
- Implement Web Application Firewall (WAF): Consider deploying a Web Application Firewall (WAF) to add an extra layer of protection. A well-configured WAF can help detect and block malicious SQL Injection attempts before they reach your application.
- Regular Backups: As a fundamental security practice, always maintain comprehensive and regular backups of your entire WordPress website, encompassing both your core files and database. This ensures you can swiftly restore your site in the unlikely event of any security breach or data compromise.
