Authenticated cross-site scripting via calendar event fields
Published Aug 16, 2022 · Updated Apr 15, 2025
Cross-site scripting in the Calendar Handler of Timetable and Event Schedule 1.4.06 allows remote authenticated users to execute browser script. The handler places attacker-controlled Subject, Location, or Description values from the adddetails data-feed request into generated content without neutralizing active markup. A low-privileged remote user must submit a crafted calendar-event value and a victim must view the resulting content; execution is confined to that victim's browser context.
