CVE-2026-1980 in WPBookit Plugin
Summary
by MITRE • 03/04/2026
The WPBookit plugin for WordPress is vulnerable to unauthorized data disclosure due to a missing authorization check on the 'get_customer_list' route in all versions up to, and including, 1.0.8. This makes it possible for unauthenticated attackers to retrieve sensitive customer information including names, emails, phone numbers, dates of birth, and gender.

The WPBookit plugin for WordPress represents a significant security vulnerability classified as CVE-2026-1980, which exposes sensitive customer data through a critical authorization flaw in its API endpoint design. This vulnerability affects all versions up to and including 1.0.8, making it a widespread concern for WordPress site administrators who have implemented this booking management solution. The flaw resides within the 'get_customer_list' route, which fails to properly validate user authentication status before processing requests, creating an exploitable pathway for malicious actors to access confidential customer information.
The technical implementation of this vulnerability stems from a fundamental failure in access control mechanisms within the plugin's routing system. The missing authorization check means that any unauthenticated user can submit requests to the 'get_customer_list' endpoint and receive a response containing comprehensive customer data sets. This represents a direct violation of the principle of least privilege and demonstrates poor input validation practices that are commonly addressed by security standards such as CWE-284, which specifically addresses improper access control issues. The vulnerability allows attackers to bypass normal authentication procedures and directly access data that should only be available to authorized administrators or users with appropriate permissions.
The operational impact of this vulnerability extends beyond simple data exposure, creating potential risks for both the website operator and their customers. Customer information including names, email addresses, phone numbers, dates of birth, and gender represents personally identifiable information that could be exploited for identity theft, social engineering attacks, or targeted phishing campaigns. The exposure of such sensitive data through an unauthenticated API endpoint creates a significant risk for compliance violations under data protection regulations such as gdpr and ccpa, potentially resulting in substantial financial penalties and reputational damage for affected organizations.
Security professionals should consider this vulnerability in the context of broader attack patterns documented in the mitre att&ck framework, particularly within the credential access and defense evasion categories. The vulnerability enables an attacker to perform reconnaissance activities without detection, gathering intelligence that could be used for more sophisticated attacks against the organization or its customers. Organizations should implement immediate mitigations including disabling the vulnerable endpoint, implementing proper authentication checks, or upgrading to patched versions of the plugin. The vulnerability also highlights the importance of regular security audits and the need for proper input validation and access control mechanisms in web applications, aligning with security best practices outlined in owasp top ten and other industry standards that emphasize the critical nature of authentication and authorization controls in preventing unauthorized data access.
