CVE-2025-6783 is a high-severity SQL Injection vulnerability affecting the GoZen Forms plugin for WordPress, developed by optinlyhq. The vulnerability exists in all versions up to and including 1.1.5, specifically within the emdedSc() function's handling of the 'forms-id' parameter. Due to insufficient escaping and lack of proper SQL query preparation, unauthenticated attackers can inject malicious SQL code by appending additional queries to the existing SQL statements. This improper neutralization of special elements (CWE-89) allows attackers to extract sensitive information from the underlying database without requiring authentication or user interaction. The vulnerability is remotely exploitable over the network (AV:N), requires no privileges (PR:N), and no user interaction (UI:N), making it particularly dangerous. Although no known exploits are currently reported in the wild, the vulnerability's CVSS score of 7.5 reflects its high impact on confidentiality, as attackers can access sensitive data. The integrity and availability of the system are not directly impacted. The vulnerability arises from insecure coding practices in the plugin's SQL query construction, highlighting the need for parameterized queries or prepared statements to prevent injection attacks. Given WordPress's widespread use and the popularity of form plugins, this vulnerability poses a significant risk to websites using GoZen Forms, especially those handling sensitive user data.

For European organizations, this vulnerability presents a serious risk to the confidentiality of data managed through WordPress sites using the GoZen Forms plugin. Attackers exploiting this flaw can extract sensitive information such as user credentials, personal data, or business-critical information stored in the database. This could lead to data breaches, regulatory non-compliance (e.g., GDPR violations), reputational damage, and potential financial penalties. Since the vulnerability is exploitable without authentication, attackers can target public-facing websites indiscriminately. Organizations in sectors such as e-commerce, healthcare, finance, and government, which often rely on WordPress for content management and use form plugins for data collection, are particularly vulnerable. The lack of known exploits in the wild currently reduces immediate risk, but the ease of exploitation and high impact make proactive mitigation essential. Additionally, the vulnerability could be leveraged as a foothold for further attacks if combined with other vulnerabilities or misconfigurations.

European organizations should immediately audit their WordPress installations to identify the use of the GoZen Forms plugin, especially versions up to 1.1.5. Since no official patch links are currently available, organizations should consider the following specific mitigations: 1) Temporarily disable or remove the GoZen Forms plugin until a patched version is released. 2) Implement Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the 'forms-id' parameter, using signature-based and anomaly detection methods. 3) Conduct thorough input validation and sanitization on all user-supplied data, particularly parameters passed to SQL queries. 4) Monitor web server and database logs for unusual query patterns or repeated access attempts to the vulnerable endpoint. 5) Prepare for rapid deployment of patches once available by maintaining an inventory of affected systems and a tested update process. 6) Educate developers and administrators on secure coding practices, emphasizing the use of parameterized queries and prepared statements to prevent SQL injection vulnerabilities in custom plugins or code. 7) Consider isolating WordPress instances or databases to limit the blast radius of potential data exfiltration.
