CVE-2025-6783 identifies a critical SQL Injection vulnerability in the GoZen Forms plugin for WordPress, specifically in the emdedSc() function's handling of the 'forms-id' parameter. The vulnerability arises from improper neutralization of special elements in SQL commands (CWE-89), where user-supplied input is not adequately escaped or parameterized before being incorporated into SQL queries. This flaw allows unauthenticated attackers to append arbitrary SQL code to existing queries, enabling them to extract sensitive data from the backend database. The vulnerability affects all versions up to and including 1.1.5 of the plugin. The CVSS 3.1 base score of 7.5 reflects its high severity, with an attack vector that requires no privileges or user interaction, and impacts confidentiality without affecting integrity or availability. The lack of authentication requirement and the network attack vector make this vulnerability particularly dangerous for publicly accessible WordPress sites using the affected plugin. No patches or official fixes are currently linked, and no known exploits have been reported in the wild, but the vulnerability's characteristics suggest it could be exploited by attackers to harvest sensitive information such as user data, credentials, or other confidential content stored in the database.

The primary impact of CVE-2025-6783 is the unauthorized disclosure of sensitive information from the database of affected WordPress sites using the GoZen Forms plugin. Attackers exploiting this vulnerability can bypass authentication and extract confidential data, potentially including user credentials, personal information, or business-critical data. This can lead to data breaches, loss of customer trust, regulatory penalties, and reputational damage. Since the vulnerability does not affect data integrity or availability, attackers cannot directly modify or disrupt services, but the confidentiality breach alone is significant. Organizations relying on this plugin for form management on their websites face increased risk of targeted data exfiltration attacks. The ease of exploitation and the lack of required privileges increase the likelihood of automated scanning and exploitation attempts, especially once public proof-of-concept exploits emerge. This threat is particularly concerning for organizations in sectors with strict data protection requirements such as finance, healthcare, and e-commerce.

To mitigate CVE-2025-6783, organizations should immediately upgrade the GoZen Forms plugin to a version that addresses this vulnerability once available. In the absence of an official patch, administrators should consider disabling or removing the plugin to eliminate exposure. As a temporary workaround, implementing Web Application Firewall (WAF) rules to detect and block suspicious SQL injection patterns targeting the 'forms-id' parameter can reduce risk. Additionally, restricting access to the affected endpoints via IP whitelisting or authentication can limit exposure. Site owners should audit their logs for unusual query patterns or access attempts to identify potential exploitation. Employing database user accounts with least privilege, limiting read access to only necessary tables, can reduce the impact of a successful injection. Regular backups and monitoring for data exfiltration indicators are recommended. Finally, developers should review and refactor the plugin code to use prepared statements and parameterized queries to prevent injection vulnerabilities.
