A stored cross-site scripting (XSS) vulnerability exists in craigk5n/webcalendar version 1.3.0. The vulnerability occurs in the 'Report Name' input field while creating a new report. An attacker can inject malicious scripts, which are then executed in the context of other users who view the report, potentially leading to the theft of user accounts and cookies.

WebCalendar v1.3.0 was discovered to contain a reflected cross-site scripting (XSS) vulnerability via the component /WebCalendarvqsmnseug2/edit_entry.php.
