Published Aug 15, 2026 · Updated Oct 14, 2026 · Assigned by Wordfence

Description

The Online Booking & Scheduling Calendar for WordPress by vcita plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'business_id' parameter in all versions up to, and including, 4.6.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
