Descriptions

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Nikola Loncar Easy Appointments allows Stored XSS.This issue affects Easy Appointments: from n/a through 3.10.7.

The Easy Appointments plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 3.11.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers , with administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only impacts multi-site installations and installations where unfiltered_html has been disabled.
