CVE-2025-69095: DT Reservation Plugin Auth Bypass Flaw

CVE-2025-69095 Overview

CVE-2025-69095 is a Missing Authorization vulnerability affecting the designthemes Reservation Plugin (dt-reservation-plugin) for WordPress. This security flaw allows attackers to exploit incorrectly configured access control security levels, potentially enabling unauthorized modification of plugin settings without proper authentication or authorization checks.

Critical Impact

Attackers can bypass authorization controls to modify plugin settings, potentially compromising reservation functionality and site integrity.

Affected Products

• designthemes Reservation Plugin (dt-reservation-plugin) version 1.7 and earlier
• WordPress sites running vulnerable versions of the plugin

Technical Details for CVE-2025-69095

Vulnerability Analysis

This vulnerability stems from CWE-862 (Missing Authorization), a common weakness where software fails to perform authorization checks when accessing resources or functionality. In the context of the dt-reservation-plugin, the application does not properly verify that users have the required permissions before allowing access to sensitive administrative functions.

The vulnerability affects all versions of the Reservation Plugin from the initial release through version 1.7. Without proper authorization controls, authenticated users with lower privilege levels (such as subscribers or contributors) may be able to access and modify plugin settings that should be restricted to administrators only.

Root Cause

The root cause of this vulnerability is the absence of capability checks in the plugin's settings management functionality. WordPress plugins should implement proper authorization using functions like current_user_can() to verify that users have appropriate capabilities before processing requests that modify settings. The dt-reservation-plugin fails to implement these checks, allowing any authenticated user to potentially alter plugin configurations.

Attack Vector

The attack requires an authenticated user to send requests to the vulnerable plugin endpoints. Since the plugin does not validate user permissions, requests to modify settings are processed regardless of the user's actual role or capabilities. This could be exploited by:

1. A malicious authenticated user with minimal privileges (subscriber level)
2. An attacker who has compromised any user account on the WordPress site
3. Exploitation through CSRF if combined with other vulnerabilities

The vulnerability allows unauthorized changes to reservation settings, which could disrupt business operations, modify pricing, or expose sensitive configuration data. For detailed technical information, see the Patchstack WordPress Vulnerability Advisory.

Detection Methods for CVE-2025-69095

Indicators of Compromise

• Unexpected modifications to Reservation Plugin settings without corresponding administrator activity
• Audit log entries showing settings changes initiated by non-administrator users
• Anomalous POST requests to plugin admin endpoints from low-privileged user sessions
• Configuration changes occurring outside normal business hours or administrative patterns

Detection Strategies

• Implement file integrity monitoring on the wp-content/plugins/dt-reservation-plugin/ directory to detect unauthorized changes
• Enable WordPress audit logging to track all plugin settings modifications and correlate with user roles
• Monitor HTTP POST requests to WordPress admin-ajax.php that reference dt-reservation-plugin actions
• Review user activity logs for privilege escalation attempts or unauthorized administrative actions

Monitoring Recommendations

• Deploy a Web Application Firewall (WAF) with rules to detect unauthorized access patterns to WordPress plugin endpoints
• Configure SIEM alerts for settings modification events from non-administrator user accounts
• Implement regular automated scans using WordPress security plugins to identify authorization bypass attempts
• Monitor for unusual patterns in authenticated user requests, particularly those targeting plugin configuration endpoints

How to Mitigate CVE-2025-69095

Immediate Actions Required

• Audit current plugin settings to identify any unauthorized modifications that may have already occurred
• Review WordPress user accounts and remove or demote any suspicious accounts with unnecessary privileges
• Temporarily disable the dt-reservation-plugin if reservation functionality is not critical until a patched version is available
• Implement additional access controls at the web server level to restrict plugin admin endpoints

Patch Information

At the time of publication, no official patch has been confirmed. Site administrators should monitor the plugin developer's official channels and the Patchstack advisory for updates regarding a security fix. Consider reaching out to the plugin developer (designthemes) to request a patched version that implements proper authorization checks.

Workarounds

• Implement a WordPress security plugin with capability to add virtual patching rules for missing authorization vulnerabilities
• Use a WordPress firewall plugin to restrict access to plugin admin functions based on user capabilities
• Add custom code to your theme's functions.php or a custom plugin to enforce capability checks on dt-reservation-plugin actions
• Restrict WordPress admin access to trusted IP addresses only using .htaccess rules or server configuration

# Example .htaccess restriction for WordPress admin area
<Files "admin-ajax.php">
    <RequireAll>
        Require ip 192.168.1.0/24
        Require ip 10.0.0.0/8
    </RequireAll>
</Files>
