CVE-2026-63431
Horilla: Missing Authorization on Payroll Component Views Exposes Employee Salary Structures and Personal Loan Records (IDOR)
Description
Horilla is an HR and CRM software. In 1.5.0-85 and earlier, payroll/views/component_views.py does not consistently authorize access in allowances_deductions_tab, view_single_allowance, and view_single_deduction before loading records selected by emp_id, allowance_id, or deduction_id. An authenticated employee can substitute those identifiers to read another employee's salary structure, allowance and deduction amounts, personal loan disbursements, and repayment schedules without owning the record or holding payroll-view permissions. No complete fixed version is available as of this review.
