CVE-2026-63431 · Severity: medium · CVSS 6.5 · Published 2026-09-25

Horilla is HR and CRM software that manages employee payroll, allowances, and personal loans. An authenticated employee can view any colleague's salary structure, allowance amounts, personal loan disbursements, and repayment schedules by manipulating URL parameters—even without payroll permissions. This exposes confidential compensation and financial data across the entire workforce.

## 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.
