Vcita · Vcita Online Booking & Scheduling Calendar · CVE-2026-14433
**Name of the Vulnerable Software and Affected Versions**
Online Booking & Scheduling Calendar for WordPress by vcita versions prior to 4.6.1
**Description**
Insufficient input sanitization and output escaping allow unauthenticated attackers to perform Stored Cross-Site Scripting (XSS), a technique where malicious scripts are permanently stored on the target server. This occurs via the `business id` parameter within the REST API endpoint. An attacker can inject arbitrary web scripts into pages that execute automatically when a user accesses the affected page.
**Recommendations**
Update the plugin to a version newer than 4.6.0.
As a temporary mitigation, restrict access to the REST API endpoint utilizing the `business id` parameter.
