HR Tech & payroll: sensitive data, simple flaws

Published on 2026-02-255 min readFlorian

HR is a priority target

Payroll and HR software contains the most sensitive enterprise data: salaries, IBANs, social security numbers, ID documents.

For more — see our HR & payroll vendor security.

What we find

  • Unprotected APIs returning complete employee lists with salaries
  • Documents in public buckets (payslips, contracts, IDs)
  • Cross-user access (manager sees all employees, not just their team)
  • Unrestricted CSV export = mass exfiltration in one click
  • For HR & Payroll vendors

    CleanIssue specializes in security reviews for HR, payroll, and recruiting software. If you're building an HRIS, payroll tool, or ATS and want an external review of your exposure before a client audit or security questionnaire, see our offer for HR & Payroll vendors.
