CVE-2025-3769 in Latepoint Plugin
Summary
by MITRE • 05/14/2025
The LatePoint – Calendar Booking Plugin for Appointments and Events plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 5.1.92 via the 'view_booking_summary_in_lightbox' due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to retrieve appointment details such as customer names and email addresses.

The CVE-2025-3769 vulnerability affects the LatePoint WordPress plugin, specifically targeting versions up to and including 5.1.92. This security flaw represents a critical Insecure Direct Object Reference vulnerability that undermines the plugin's access control mechanisms. The vulnerability manifests through the 'view_booking_summary_in_lightbox' functionality, where the plugin fails to properly validate user-controlled input parameters. Attackers can exploit this weakness by manipulating the input key to bypass authentication requirements and gain unauthorized access to sensitive booking information. The vulnerability stems from inadequate sanitization and validation of parameters passed to the plugin's core functionality, creating an attack surface that allows unauthorized data exposure.
The technical implementation of this vulnerability allows attackers to directly reference objects within the plugin's backend without proper authorization checks. When the 'view_booking_summary_in_lightbox' parameter is manipulated, the plugin processes the request without validating whether the requesting user has legitimate access rights to view the specific booking data. This weakness directly maps to CWE-284, which addresses inadequate access control mechanisms, and aligns with ATT&CK technique T1213.002 related to data from information repositories. The vulnerability exists because the plugin does not implement proper access control validation before processing user requests, enabling attackers to construct malicious requests that target specific booking records.
The operational impact of this vulnerability is severe as it exposes sensitive customer information including names and email addresses without requiring authentication. Attackers can systematically enumerate booking records by manipulating the vulnerable parameter, potentially gaining access to extensive customer databases. This exposure creates significant privacy risks for users and organizations relying on the plugin for appointment scheduling. The vulnerability affects any WordPress installation using the affected plugin version, making it particularly dangerous as it requires minimal technical expertise to exploit. Organizations may face regulatory compliance violations under data protection laws such as GDPR and CCPA due to unauthorized data access and exposure of personal information.
Mitigation strategies should focus on immediate plugin updates to versions that address the access control flaw, as well as implementing additional security measures. Administrators should ensure they upgrade to the latest plugin version where the vulnerability has been patched, typically involving proper input validation and access control enforcement. Network-level protections such as web application firewalls can provide additional defense-in-depth measures by monitoring for suspicious parameter manipulation patterns. Regular security audits of WordPress plugins should include validation of access control mechanisms, particularly for plugins handling sensitive user data. The vulnerability highlights the importance of implementing proper input validation and access control checks in web applications, aligning with security best practices outlined in OWASP Top Ten and NIST cybersecurity frameworks. Organizations should also consider implementing rate limiting and monitoring for unusual access patterns to detect potential exploitation attempts.
