Munshi (by Petpooja) before 2026-07-13 contained a stored cross-site scripting vulnerability that allows authenticated users to inject malicious markup through item descriptions or messages submitted in the Purchase Inquiry thread (/purchase-inquiry/thread/{thread-id}), which is assigned to innerHTML during rendering before text cleaning completes. Attackers can store a payload that executes in the browser of another user who opens the affected thread, achieving JavaScript execution and full-page defacement that re-triggers whenever the thread is reopened.
