SQL Injection in WeGIA Prior to 3.8.6

Publication date: 2026-10-14

Last updated on: 2026-10-15

Assigner: GitHub, Inc.

Description
WeGIA is a web manager for charitable institutions. Prior to 3.8.6, the unauthenticated web/html/socio/sistema/cadastro_cobrancas_geracao.php endpoint accepts form-encoded POST data through extract($_REQUEST) and interpolates codigo, descricao, data_emissao, data_vencimento, data_pagamento, valor, valor_pago, status, link_cobranca, link_boleto, linha_digitavel, and id_socio into a raw INSERT statement. Numeric parameters are unquoted and unvalidated, while string parameters can break out of their single-quoted SQL context. A remote attacker can execute arbitrary SQL to read or modify billing, member, employee, permission, and credential data or to delete database tables. This issue is fixed in version 3.8.6.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

CVE-2026-55684 is a critical SQL injection flaw in WeGIA software versions 3.8.5 and earlier. The vulnerability exists in the cadastro_cobrancas_geracao.php file where unauthenticated attackers can inject malicious SQL commands through POST requests. The application uses extract($_REQUEST) to process form data and directly embeds unfiltered parameters into raw SQL INSERT statements without validation or sanitization.

Detection Guidance

To detect this vulnerability, check if your WeGIA instance is running version 3.8.5 or earlier. Inspect the file html/socio/sistema/cadastro_cobrancas_geracao.php for the use of extract($_REQUEST) and direct SQL query interpolation. Look for POST requests to the endpoint /web/html/socio/sistema/cadastro_cobrancas_geracao.php with parameters like codigo, descricao, or id_socio.

Impact Analysis

An attacker could exploit this to read sensitive data like billing records, member information, employee details, permissions, or credential data. They could modify existing records, delete database tables, or bypass authentication by extracting admin password hashes. The attack requires no authentication and can be performed remotely.

Compliance Impact

This vulnerability likely violates multiple compliance requirements including GDPR's data protection principles (Article 5) and HIPAA's security rule (45 CFR 164.308). It enables unauthorized access to protected health information or personal data, potentially leading to regulatory fines and legal consequences for organizations failing to implement proper security controls.

Mitigation Strategies

Immediately upgrade WeGIA to version 3.8.6 or later. If upgrading is not possible, apply input validation for all POST parameters and replace direct SQL queries with prepared statements using PDO. Disable the vulnerable endpoint if not required.
