OpenSupports 4.11.0 — SQL Injection

The endpoint POST /api/staff/get-new-tickets concatenates the user-controlled parameter departmentId directly into the SQL WHERE clause without parameter binding. As a result, an authenticated staff user (level ≥ 1) can inject SQL to alter the filter logic, effectively bypassing department scoping and disclosing tickets beyond their intended access.This issue affects OpenSupports: 4.11.0.
