AnalysisAI
Authorization bypass in jaychouchannel's Tourism-Management-System allows authenticated remote users to access or modify ticket order records belonging to other users by manipulating the ID parameter in CRUD operations against MenpiaodingdanController.java. This is a classic Insecure Direct Object Reference (IDOR) pattern where the application fails to verify that the requesting user owns the referenced resource. …
