What is known
WeGIA is a web manager for charitable institutions. Prior to 3.8.6, unauthenticated POST requests to web/html/socio/sistema/cadastro_cobranca.php can place a quoted SQL expression in the codigo parameter, which extract($_REQUEST) passes into the WHERE codigo= clause of an UPDATE statement without validation or parameter binding. Quoting the value bypasses MariaDB type conversion for the VARCHAR column and permits arbitrary SQL execution without a session. An attacker can read or modify database content, including user credential hashes and billing records in the cobrancas table. This issue is fixed in version 3.8.6.
Business impact
Successful exploitation of CVE-2026-55680, a critical vulnerability (CVSS 9.8) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action
Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
