CVE-2026-54671: WeGIA: Authorization Bypass via Empty Resource Array in InternoControle

• Severity: high (CVSS 8.8 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.6% probability of exploitation in the next 30 days
• Public exploit or detection template: none known

• Weakness: CWE-639

Description

WeGIA is a web manager for charitable institutions. Prior to 3.8.5, WeGIA maps InternoControle to an empty resource array in web/controle/control.php, and verificarPermissao in web/dao/MiddlewareDAO.php treats that empty array as unconditional access for every authenticated user. The methods in web/controle/InternoControle.php, including listarUm, alterar, and excluir, accept user-controlled id or idInterno values without verifying ownership, allowing a low-privileged user to read, modify, or delete another person's records and expose personal, identity, address, medical, and family information. The advisory notes that a self-referencing load bug can crash this controller in the reported revision, but the empty-resource authorization pattern and affected methods remain the vulnerability under review. This issue is fixed in version 3.8.5.
