Administrator session compromise via stored reservation XSS
Published Jul 19, 2025 · Updated Jul 21, 2025
Stored XSS in CampCodes Online Movie Theater Seat Reservation System 1.0 allows remote attackers to execute script in an administrator's browser. The reserve form accepts Firstname and Lastname values without sanitization or output escaping, stores them, and renders them on the administrator's Books page. Submitting a reservation requires no account, but exploitation requires an administrator to view the booking, enabling session theft or actions in that administrator's context.
