CVE-2025-67577 identifies a missing authorization vulnerability in the Easy Form Builder plugin developed by hassantafreshi, affecting all versions up to and including 3.8.20. The vulnerability arises from incorrectly configured access control security levels, which fail to properly verify whether a user has the necessary permissions to perform certain actions within the plugin. This misconfiguration can allow an attacker to bypass authorization checks and execute unauthorized operations, such as modifying form data, accessing sensitive information, or altering form configurations. The vulnerability does not require prior authentication or user interaction, increasing its risk profile. Although no public exploits have been reported, the flaw is significant because form builders are often integrated into websites to collect user input, making unauthorized access potentially impactful. The lack of a CVSS score indicates that the vulnerability is newly published and not yet fully assessed, but the nature of missing authorization typically leads to high severity due to the direct compromise of access controls. The vulnerability affects a widely used plugin, suggesting a broad attack surface, especially in environments where the plugin is exposed on public-facing websites. The absence of patch links suggests that a fix may not yet be available, emphasizing the need for immediate mitigation strategies.

For European organizations, this vulnerability could lead to unauthorized access to form data, which may include personally identifiable information (PII), business-sensitive data, or credentials submitted through forms. The integrity of form configurations could also be compromised, potentially allowing attackers to alter form behavior or inject malicious content. This can result in data breaches, reputational damage, and compliance violations under regulations such as GDPR. Organizations relying on Easy Form Builder for customer interactions, lead generation, or internal workflows are particularly at risk. The ease of exploitation without authentication increases the threat level, potentially enabling attackers to conduct reconnaissance or escalate attacks within the network. The availability impact is lower but could occur if attackers disrupt form functionality. Overall, the vulnerability threatens confidentiality and integrity primarily, with moderate availability concerns.

Until an official patch is released, organizations should implement strict access controls to limit who can access the Easy Form Builder interfaces, ideally restricting it to trusted administrative users only. Network-level restrictions such as IP whitelisting or VPN access can reduce exposure. Monitoring and logging access to the plugin’s endpoints should be enhanced to detect suspicious activity. If possible, temporarily disabling or uninstalling the plugin can eliminate the risk. Web application firewalls (WAFs) can be configured to block unauthorized requests targeting the plugin’s known endpoints. Organizations should also review and harden their overall access control policies and conduct thorough audits of form data and configurations for signs of tampering. Once patches become available, prompt application is critical. Additionally, educating administrators about the risks and signs of exploitation can improve detection and response.
