CVE-2026-63431: Horilla: Missing Authorization on Payroll Component Views Exposes Employee Salary Structures and Personal Loan Records (IDOR)

• Severity: medium (CVSS 6.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.2% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-09-25 · updated 2026-09-30
• Weakness: CWE-862

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.
