CVE-2026-5798Network attack vector

Authenticated employee data disclosure via employeeID manipulation

Published May 14, 2026 · Updated May 14, 2026

Authorization bypass in STEL Order 3.25.1 and earlier allows remote authenticated users to read other employees' records. The /app/FrontController endpoint uses a caller-controlled employeeID to retrieve employee records without enforcing backend permission or company-account scope. Any authenticated user can expose names, roles, job titles, and vacation records; no integrity or availability impact is reported.
