CVE-2021-37213Network attack vector

Employee check-in disclosure via user-controlled record references

Published Aug 9, 2021 · Updated Sep 17, 2024

IDOR in Larvata Digital Technology FLYGO through 2021.4e allows remote authenticated users to read other employees' check-in records. The check-in record page accepts an employee ID and date from request parameters and retrieves the referenced employee's record without enforcing object-level authorization. A general-user account is required, and the bounded impact is disclosure of another employee's attendance data.
