CVE-2025-69340: Ultimate Booking Addon Auth Bypass Flaw

CVE-2025-69340 Overview

A Missing Authorization vulnerability has been identified in the BuddhaThemes WeDesignTech Ultimate Booking Addon plugin for WordPress. This broken access control flaw allows unauthenticated attackers to exploit incorrectly configured access control security levels, potentially exposing sensitive booking data and system information to unauthorized parties.

Critical Impact

Unauthenticated attackers can bypass access controls to read sensitive booking information and potentially compromise user data stored within the WordPress booking system.

Affected Products

• WeDesignTech Ultimate Booking Addon versions through 1.0.3
• WordPress installations running the vulnerable plugin
• Sites using BuddhaThemes WeDesignTech booking functionality

Technical Details for CVE-2025-69340

Vulnerability Analysis

This vulnerability is classified as CWE-862 (Missing Authorization), a critical weakness where the application fails to perform authorization checks before allowing access to sensitive functionality or data. In the context of the WeDesignTech Ultimate Booking Addon, the plugin does not properly verify that users have appropriate permissions before granting access to protected resources.

The flaw enables network-based attacks requiring no authentication or user interaction. An attacker can remotely access the vulnerable endpoints without any prior privileges, making this a low-complexity attack with significant potential for information disclosure. The impact is primarily focused on confidentiality, allowing unauthorized read access to sensitive data while integrity and availability remain unaffected.

Root Cause

The root cause of CVE-2025-69340 lies in the plugin's failure to implement proper authorization checks on sensitive endpoints and functions. The WeDesignTech Ultimate Booking Addon does not validate user roles or capabilities before exposing booking data, administrative functions, or other protected resources. This missing authorization mechanism allows any unauthenticated user to access functionality that should be restricted to authenticated administrators or booking managers.

Attack Vector

The attack vector is network-based, allowing remote exploitation without any authentication requirements. An attacker can craft requests to the vulnerable plugin endpoints directly, bypassing the intended access control restrictions. Since no user interaction is required and the attack complexity is low, this vulnerability presents a straightforward exploitation path for malicious actors seeking to harvest booking data, customer information, or other sensitive content managed by the plugin.

The exploitation typically involves:

1. Identifying WordPress installations running the vulnerable plugin version
2. Sending crafted HTTP requests to plugin endpoints that lack authorization checks
3. Retrieving sensitive booking information, customer data, or administrative content
4. Potentially chaining with other vulnerabilities for further system compromise

Detection Methods for CVE-2025-69340

Indicators of Compromise

• Unusual HTTP requests to WeDesignTech Ultimate Booking Addon endpoints from unauthenticated sessions
• Access logs showing requests to booking data endpoints without valid WordPress authentication cookies
• Unexpected data exports or bulk retrieval of booking records
• Anonymous requests accessing administrative booking functions

Detection Strategies

• Monitor WordPress access logs for unauthenticated requests to /wp-content/plugins/wedesigntech-ultimate-booking-addon/ endpoints
• Implement Web Application Firewall (WAF) rules to detect and block suspicious access patterns targeting the booking plugin
• Deploy endpoint monitoring to alert on unusual plugin activity patterns
• Review plugin-specific database queries for unauthorized data access attempts

Monitoring Recommendations

• Enable detailed logging for the WeDesignTech Ultimate Booking Addon plugin
• Configure real-time alerts for access control bypass attempts
• Implement rate limiting on plugin endpoints to detect enumeration attacks
• Regularly audit booking data access patterns for anomalous behavior

How to Mitigate CVE-2025-69340

Immediate Actions Required

• Disable the WeDesignTech Ultimate Booking Addon plugin immediately if not critical to operations
• Implement temporary access restrictions at the web server level to block unauthenticated access to plugin endpoints
• Review access logs to identify any potential exploitation that may have already occurred
• Consider using a Web Application Firewall to add an additional layer of access control protection

Patch Information

Check the Patchstack Vulnerability Report for the latest patch information and update the plugin to a version newer than 1.0.3 when a security fix becomes available. Contact BuddhaThemes for information about patched versions.

Workarounds

• Implement .htaccess rules to restrict access to plugin directories for authenticated users only
• Use a security plugin to add capability checks on WordPress AJAX and REST API endpoints
• Configure IP whitelisting for administrative booking functions if a patch is not yet available
• Consider temporarily replacing the plugin with an alternative booking solution until a secure version is released

# Apache .htaccess restriction for plugin directory
# Add to /wp-content/plugins/wedesigntech-ultimate-booking-addon/.htaccess
<Files "*.php">
  Order Deny,Allow
  Deny from all
  Allow from 127.0.0.1
</Files>

# Note: Test thoroughly as this may break legitimate functionality
# This is a temporary measure until an official patch is available
