Technical details
The vulnerability is a missing authorization (CWE-862) in payroll/views/component_views.py where three views (allowances_deductions_tab, view_single_allowance, view_single_deduction) lack permission checks before returning employee-specific payroll records based on URL-supplied emp_id, allowance_id, or deduction_id. An authenticated user with no payroll-specific permissions can exploit this via network request by substituting arbitrary object IDs. A partial fix exists in the referenced commit, but no complete patched release is available.
