EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 64% of all CVEs by exploit prediction. 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 is a web manager for charitable institutions. Prior to 3.8.5, web/html/socio/sistema/controller/deletar_socios.php exposes an unauthenticated GET endpoint whose chave parameter is checked only against a hardcoded chave_correta value embedded in the public source repository. A remote attacker who obtains that value can reach the endpoint's TRUNCATE TABLE operations for the endereco, pessoafisica, pessoajuridica, and socio tables without an administrative session or application authorization, permanently destroying member and contributor records. The attack requires the affected tables to exist and the web process database account to possess truncation privileges. This issue is fixed in version 3.8.5.
