CVE-2026-76634

MEDIUMPre-NVD 6.56.5
EchelonGraph scoreLOW confidence

This medium-severity CVE scores 6.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). 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).

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.
