The Easy Appointments plugin for WordPress contains a vulnerability (CVE-2025-49398) that affects versions up to and including 3.12.14. This vulnerability allows unauthenticated attackers to execute arbitrary shortcodes due to improper validation of values before running doshortcode (Rapid7, [Patchstack](https://vdp.patchstack.com/database/Wordpress/Plugin/easy-appointments/vulnerability/wordpress-easy-appointments-plugin-3-12-14-content-injection-vulnerability?s_id=cve)).
