CVE-2026-2262 Scanner

Easy Appointments WordPress Plugin is widely utilized by small businesses and independent service providers to seamlessly manage customer appointments online. It offers customizable scheduling options, integration with Google Calendar, and email notifications to enhance booking efficiency. Though primarily employed in service-based sectors, it's also popular among educational institutions and healthcare providers for managing consultations and appointments. The plugin's ease of use and flexibility have enticed a broad range of users across different industries. Its API accessibility facilitates integrations with third-party applications to streamline operations and enhance user experience. Despite its benefits, security vulnerabilities pose significant risks that need addressing to prevent unauthorized data access.

The Information Disclosure vulnerability in Easy Appointments WordPress Plugin arises from a lack of authentication requirements in accessing sensitive data. Unauthorized users could exploit the affected REST API endpoint to retrieve customers' confidential appointment details. This flaw exists due to overly permissive access settings, allowing individuals without proper permissions to succeed in data extraction. The plugin's specific vulnerability allows exposure of intricate personal details, such as emails, phone numbers, and IP addresses. Security lapses like this can undermine user trust, exposing organizations to reputational damage and regulatory scrutiny. Continuous vigilance and timely updates are essential in mitigating such privacy risks.

The vulnerability is primarily located within the REST API endpoint /wp-json/wp/v2/eablocks/ea_appointments/, which is improperly secured. The permission_callback function fails to adequately restrict access, enabling unauthorized parties to query sensitive information. The exposure includes pivotal identifying details such as customer names, contact details, and appointment-related specifics. Attackers can leverage these weaknesses via simple HTTP requests, given the conditions are met for successful data fetch. Partially unverified permission settings inadvertently encompass all user roles, allowing broad access. Ensuring restricted access protocols for significant endpoints would curb unauthorized disclosures.

Malicious exploitation of this vulnerability could lead to extensive unauthorized data aggregates that jeopardize privacy and compliance frameworks. Personal customer data, once compromised, may facilitate phishing attacks or identity theft by cybercriminals. Service providers relying on this plugin could face substantial legal ramifications and financial penalties if user privacy rights are violated. Unauthorized access is also a gateway to wider attacks, potentially jeopardizing other linked systems or data sets. Organizations failing to secure their plugin installations risk losing client trust and facing devastating impacts on their reputation within their industry.
