EchelonGraph scoreMEDIUM confidence

This critical-severity CVE scores 9.1 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.6%, top 55% 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, the contribution request dispatcher in web/html/contribuicao/controller/control.php accepts attacker-controlled nomeClasse and metodo values without a complete controller and method allowlist, exempts sensitive ContribuicaoLogController operations from authentication, and constructs a controller include path without canonical directory containment. An unauthenticated remote attacker can invoke getContribuicoesLogJSON, sincronizarStatus, registrarFaturas, and other sensitive methods to disclose contribution and donation records or trigger financial workflow operations. A traversal-shaped nomeClasse value can also cause require_once to include an accessible PHP or configuration file outside the intended controller directory, exposing source code, credentials, or other sensitive local data. This issue is fixed in version 3.8.5.
