## Technical details

The /clientApi/book/myBookDetail endpoint in Fuint performs insufficient authorization checks, allowing authenticated users to query arbitrary bookId values and retrieve booking details belonging to other users. Since bookIds are auto-incrementing, attackers can enumerate the full range to extract all booking records. The vulnerability requires prior authentication but no other preconditions.
