Summary

WeGIA before 3.9.2 contains an insecure direct object reference vulnerability in the employee profile page that allows authenticated attackers to access arbitrary employee records by injecting an id_pessoa parameter through a request extraction function that overwrites the session-derived identifier. Attackers can enumerate all user identifiers to retrieve full profile data for any employee account, including name, CPF, address, contact details, and administrative flags.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of LabRedesCefetRJ/WeGIA published their own advisory on GitHub. Reviewed sources take precedence over it.
