CVE-2025-14982 Overview
The Booking Calendar plugin for WordPress contains a Missing Authorization vulnerability that allows authenticated attackers with Subscriber-level access to view all booking records in the database. This flaw exposes sensitive personally identifiable information (PII) including names, email addresses, phone numbers, physical addresses, payment status, booking costs, and booking hashes belonging to other users. All versions up to and including 10.14.11 are affected by this vulnerability.
Critical Impact
Authenticated attackers with minimal privileges (Subscriber-level) can access all booking data in the database, exposing sensitive customer PII and financial information across the entire WordPress installation.
Affected Products
- Booking Calendar plugin for WordPress versions up to and including 10.14.11

Technical Details for CVE-2025-14982
Vulnerability Analysis
This vulnerability stems from a Missing Authorization issue (CWE-862) in the Booking Calendar plugin's booking records retrieval functionality. The plugin fails to properly verify that authenticated users have the appropriate permissions before allowing access to booking data. As a result, any authenticated user with at least Subscriber-level privileges can query and retrieve booking information that should be restricted to administrators or the booking owners themselves.
The exposure affects multiple data points within booking records, making this a significant privacy concern for WordPress sites using this plugin for appointment or reservation management. Customer data including contact information, addresses, and financial details related to bookings becomes accessible to unauthorized users.
Root Cause
The root cause is the absence of proper capability checks in the plugin's booking listing and SQL query functions. Code analysis reveals that the affected components in bookings__listing.php and bookings__sql.php do not adequately verify user roles or capabilities before executing database queries that return booking records. The WordPress Booking Listings Code and WordPress Booking SQL Code show the affected areas where authorization checks are missing.
Attack Vector
The attack is network-based and requires only low-privileged authentication. An attacker needs to:
- Obtain or create a Subscriber-level account on the target WordPress site
- Access the booking management functionality through the plugin's interface or API endpoints
- Query the booking database to retrieve records belonging to other users
The vulnerability does not require user interaction and can be exploited directly by any authenticated user with minimal privileges. The Wordfence Vulnerability Report provides additional details on the exploitation scenario.
Detection Methods for CVE-2025-14982
Indicators of Compromise
- Unusual access patterns to booking records by low-privileged user accounts
- Subscriber-level accounts accessing booking administration pages or endpoints
- Unexpected database queries against booking tables from non-administrator sessions
- Evidence of bulk data retrieval from booking records
Detection Strategies
- Monitor WordPress access logs for Subscriber-level users accessing booking management endpoints
- Implement database query logging to detect unauthorized access patterns to booking tables
- Review user activity logs for accounts that access booking data beyond their permission scope
- Deploy web application firewall (WAF) rules to detect anomalous booking data access patterns
Monitoring Recommendations
- Enable detailed logging for the Booking Calendar plugin's administrative functions
- Configure alerts for Subscriber-level accounts accessing administrative plugin endpoints
- Monitor for data exfiltration patterns involving customer PII fields
- Audit user sessions that interact with booking records without appropriate role assignments
How to Mitigate CVE-2025-14982
Immediate Actions Required
- Update the Booking Calendar plugin to a version newer than 10.14.11 that includes the security fix
- Audit existing user accounts to identify any unauthorized Subscriber-level accounts
- Review access logs for signs of prior exploitation or unauthorized data access
- Consider temporarily restricting Subscriber-level capabilities until the update is applied
Patch Information
Security patches are available through the WordPress plugin repository. The fixes are documented in WordPress Booking Changeset 3432649 and WordPress Booking Changeset 3436482. Update immediately through the WordPress admin dashboard or via WP-CLI:
# Update Booking Calendar plugin via WP-CLI
wp plugin update booking
# Verify the installed version
wp plugin get booking --field=version
Workarounds
- Temporarily disable the Booking Calendar plugin if an immediate update is not possible
- Remove or demote any unnecessary Subscriber-level accounts until the patch is applied
- Implement additional access controls at the web server level to restrict booking endpoints
- Use a security plugin to enforce capability checks on plugin functionality
