WordPress Plugin Vulnerabilities
Availability Calendar < 1.2.2 - Authenticated Stored Cross-Site Scripting
Description
The plugin does not sanitise or escape its Category Names before outputting them in page/post where the associated shortcode is embed, allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html is disallowed
Proof of Concept
Create a new category via the plugin (/wp-admin/admin.php?page=owaccategory), add the following payload in the Name field: <script>alert(/XSS/)</script>, then view a page/post where the associated Category Shortcode is embed
