CVE-2025-68515 Overview
CVE-2025-68515 is a Sensitive Data Exposure vulnerability affecting the WP Booking System WordPress plugin developed by Roland Murg. The vulnerability stems from an Insertion of Sensitive Information Into Sent Data weakness (CWE-201) that allows attackers to retrieve embedded sensitive data from the plugin's communications.
This security flaw enables unauthorized actors to extract confidential information that should not be exposed through normal data transmission channels. The vulnerability affects all versions of WP Booking System through version 2.0.19.12.
Critical Impact
Attackers can retrieve sensitive data embedded in plugin communications, potentially exposing booking details, customer information, or other confidential data processed by the WP Booking System plugin.
Affected Products
- WP Booking System WordPress plugin versions through 2.0.19.12
- WordPress sites utilizing the WP Booking System plugin by Roland Murg

Technical Details for CVE-2025-68515
Vulnerability Analysis
The vulnerability falls under CWE-201 (Insertion of Sensitive Information Into Sent Data), which occurs when an application transmits sensitive data in a manner that makes it accessible to unauthorized parties. In the context of WP Booking System, the plugin improperly handles sensitive information during data transmission, allowing attackers to intercept or retrieve this embedded data.
WordPress booking plugins typically process and transmit various types of sensitive information including customer names, contact details, booking dates, and potentially payment-related information. When such data is improperly embedded in sent communications without adequate protection, it creates an opportunity for data exfiltration.
Root Cause
The root cause of this vulnerability is the improper handling of sensitive data within the WP Booking System plugin's data transmission mechanisms. The plugin fails to adequately sanitize or protect sensitive information before including it in outgoing data payloads, violating the principle of data minimization and secure data handling.
This type of vulnerability typically arises from:
- Embedding sensitive data in responses or requests where it is not needed
- Failing to implement proper access controls on data endpoints
- Including debug or verbose information in production communications
- Improper serialization of objects containing sensitive fields
Attack Vector
An attacker can exploit this vulnerability by intercepting or querying the data transmitted by the WP Booking System plugin. The attack does not require authentication in most sensitive data exposure scenarios, making it accessible to external threat actors.
The exploitation process typically involves:
- Identifying endpoints or data channels used by the WP Booking System plugin
- Capturing or requesting data from these channels
- Extracting sensitive information embedded within the responses
- Utilizing the exposed data for further attacks or unauthorized access
Technical details regarding the specific exploitation methodology can be found in the Patchstack Vulnerability Report.
Detection Methods for CVE-2025-68515
Indicators of Compromise
- Unusual data requests to WP Booking System plugin endpoints
- Unexpected access patterns to booking-related API endpoints
- Evidence of data scraping or automated queries targeting plugin functionality
- Suspicious outbound data transfers containing booking or customer information
Detection Strategies
- Monitor web server logs for abnormal access patterns to WP Booking System endpoints
- Implement Web Application Firewall (WAF) rules to detect data exfiltration attempts
- Review plugin network traffic for sensitive data leakage using packet inspection tools
- Audit user activity logs for unauthorized access to booking data
Monitoring Recommendations
- Enable detailed logging for all WP Booking System plugin activities
- Configure alerts for bulk data access or unusual query patterns
- Implement real-time monitoring for data exposure incidents
- Regularly audit plugin configuration and access controls
How to Mitigate CVE-2025-68515
Immediate Actions Required
- Update WP Booking System plugin to the latest version that addresses this vulnerability
- Review and audit any sensitive data that may have been exposed
- Implement additional access controls on booking data endpoints
- Consider temporarily disabling the plugin until a patch is applied
Patch Information
Users should update the WP Booking System plugin beyond version 2.0.19.12 to remediate this vulnerability. Check the WordPress plugin repository or the vendor's official channels for the latest secure version. For detailed patch information, refer to the Patchstack Vulnerability Report.
Workarounds
- Restrict access to the WordPress admin panel and plugin settings to trusted IP addresses only
- Implement a Web Application Firewall (WAF) with rules to filter sensitive data in responses
- Disable any unnecessary plugin features that may expose additional data endpoints
- Consider using server-side data masking for sensitive booking information
# WordPress plugin update via WP-CLI
wp plugin update wp-booking-system --version=latest
# Verify current plugin version
wp plugin list --name=wp-booking-system --fields=name,version,status
