This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2% (10th percentile of EPSS-scored CVEs). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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.
