High advisory for Munshi (by Petpooja)

Advisory overview

Munshi (by Petpooja) before 2026-06-17 contained a broken object level authorization vulnerability that allows authenticated attackers to access another user's purchase inquiry by manipulating the thread identifier in the GET /purchase-inquiry/thread/{thread-id} endpoint. Attackers can modify the thread ID to read supplier communication and quotation-related content belonging to other users, resulting in unauthorized disclosure of sensitive business information outside their access scope.
