Time-Based SQL Injection in WP Booking System WordPress Plugin

Publication date: 2026-10-10

Last updated on: 2026-10-10

Assigner: Wordfence

Description
The WP Booking System – Booking Calendar plugin for WordPress is vulnerable to time-based SQL Injection via the 'current_month' parameter in all versions up to, and including, 2.1.0.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with subscriber-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This is a regression vulnerability — a capability check introduced in versions 2.0.19.11–2.0.19.14 to address CVE-2024-50425 was removed in version 2.1, meaning any authenticated subscriber-level account can reach the vulnerable handler with no nonce validation required.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

The WP Booking System – Booking Calendar plugin for WordPress has a SQL injection vulnerability in versions up to 2.1.0.1. The flaw exists in the 'current_month' parameter due to improper escaping and lack of query preparation. Authenticated attackers with subscriber-level access or higher can inject malicious SQL queries to extract sensitive database information. This is a regression of a previously patched issue (CVE-2024-50425) where a capability check was removed in version 2.1, allowing access without nonce validation.

The vulnerability enables attackers to manipulate SQL queries, potentially accessing unauthorized data such as user credentials or other sensitive information stored in the database.

Detection Guidance

To detect this vulnerability, inspect WordPress sites using the WP Booking System – Booking Calendar plugin versions up to 2.1.0.1. Check for unusual SQL query patterns or unauthorized database access attempts. Enable WordPress debug logs and monitor for errors related to SQL syntax or failed queries.

Impact Analysis

If you use the WP Booking System plugin with versions up to 2.1.0.1, an attacker with a subscriber-level account could exploit this to steal sensitive data from your WordPress database. This includes user information, booking details, or other confidential data. The attack requires authentication but no additional privileges beyond subscriber access.

The impact includes potential data breaches, unauthorized access to personal or financial information, and compromise of the entire WordPress site if database credentials are exposed.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR, HIPAA, or other data protection regulations if it results in unauthorized access to personal data. GDPR requires protection of personal data, and a breach could lead to fines or legal consequences. HIPAA mandates strict controls for protected health information, and a similar breach could violate compliance requirements.

Organizations using this plugin may face regulatory penalties, reputational damage, and mandatory breach notifications if sensitive data is compromised through this vulnerability.

Mitigation Strategies

Immediately update the WP Booking System – Booking Calendar plugin to the latest version beyond 2.1.0.1. If an update is unavailable, consider disabling the plugin until a patch is released. Review user roles and permissions to ensure no unauthorized subscriber-level accounts have excessive access.
