CVE-2026-65758 in Convert Forms Plugin
Summary
by MITRE • 07/23/2026
The front-end Submissions view did not enforce access control. An unauthenticated visitor could therefore list a form's submissions.
Once again VulDB remains the best source for vulnerability data.

This vulnerability represents a critical access control flaw that undermines the fundamental security posture of web applications. The issue manifests when a front-end submissions interface fails to properly authenticate and authorize users before granting access to sensitive data. An unauthenticated visitor can exploit this weakness to enumerate all form submissions without requiring valid credentials or proper authorization. This type of vulnerability directly violates the principle of least privilege and demonstrates a failure in implementing proper authentication mechanisms.
The technical implementation flaw stems from inadequate input validation and authorization checks within the application's access control system. When users attempt to access form submission data through the front-end interface, the system should verify that the requester possesses appropriate permissions before returning any sensitive information. However, the current implementation appears to bypass these security controls entirely, allowing anonymous access to potentially confidential data. This weakness falls under the category of improper access control as defined by CWE-285, which specifically addresses authorization failures that permit unauthorized users to access protected resources.
The operational impact of this vulnerability extends beyond simple information disclosure to encompass potential data breaches and privacy violations. An attacker could systematically enumerate all submissions from forms that contain sensitive personal information, financial data, or proprietary business details. This capability enables comprehensive data harvesting without detection, as the access occurs through legitimate application interfaces rather than through more obvious attack vectors. The vulnerability creates a persistent threat that remains active until properly patched, potentially exposing thousands of records over time.
Organizations should immediately implement robust authentication mechanisms and access control validation for all submission interfaces. The recommended mitigations include enforcing strict session management, implementing proper role-based access controls, and ensuring that all data access requests undergo thorough authorization checks. Additionally, regular security testing including penetration testing and vulnerability scanning should be conducted to identify similar access control weaknesses across the application landscape. This vulnerability aligns with ATT&CK technique T1213 which addresses data access and extraction through unauthorized application interfaces, emphasizing the need for comprehensive access control measures throughout the application architecture.
The remediation process requires comprehensive code review of all front-end submission interfaces to ensure proper authentication enforcement. Security controls should be implemented at multiple layers including application logic, database access controls, and network-level protections. Organizations must also establish monitoring protocols to detect unusual access patterns that might indicate exploitation attempts, while maintaining detailed audit logs of all data access activities for forensic analysis purposes.
