Appointmind <= 4.1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting

Published Sep 17, 2025 · Updated Apr 8, 2026 · Assigned by Wordfence

Description

The Appointmind plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'appointmind_calendar' shortcode in all versions up to, and including, 4.1.0 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
