Booking Calendar Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Booking Calendar plugin for WordPress, affecting all versions through 10.14.1. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Administrator-level access to inject arbitrary scripts. These scripts execute when a user accesses the compromised page.

Impact

Remediation

Users are advised to update the Booking Calendar plugin to version 10.14.2 or a newer patched version.
