CVE-2026-42871

WeGIA is a web manager for charitable institutions. Prior to version 3.6.2, an authenticated SQL Injection vulnerability was identified in the Atendido_ocorrenciaControle endpoint via the id_memorando parameter. This flaw allows for full database exfiltration, exposure of sensitive PII, and potential arbitrary file reads in misconfigured environments. This vulnerability is fixed in 3.6.2.

In WeGIA prior to 3.8.6, the unauthenticated cadastro_cobrancas_geracao.php endpoint accepts POST data via extract($_REQUEST) and inserts it directly into an INSERT statement. Numeric parameters are unquoted and unvalidated, while string parameters can break out of their SQL context. A remote attacker can execute arbitrary SQL to read or modify billing, member, employee, permission, and credential data, or delete database tables.

In WeGIA prior to 3.8.6, the unauthenticated cadastro_cobranca.php endpoint accepts POST input via extract($_REQUEST) and directly incorporates valor, valor_pago, id_pessoa, id_socio, and id_sociotipo into UPDATE, INSERT, and SELECT statements without prepared statements. A remote attacker can execute arbitrary SQL to read or modify WeGIA database content, including billing records and credential data. The same SQL access can delete or truncate tables, causing loss of application data.

In WeGIA 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.

In WeGIA (a web manager for charitable institutions) prior to 3.8.5, the deletar_socios.php endpoint is accessible without authentication, and its chave parameter is checked only against a hardcoded value embedded in the public repository. An attacker who knows that value can trigger TRUNCATE TABLE operations on the endereco, pessoafisica, pessoajuridica, and socio tables, permanently destroying member and contributor records.

In WeGIA 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 attacker can invoke sensitive methods, disclose contribution and donation records, trigger financial operations, and include files outside the intended controller directory.

WeGIA is a Web Manager for Charitable Institutions. Prior to 3.6.2, a Reflected Cross-Site Scripting (XSS) vulnerability was discovered in the WeGIA system, specifically within the html/memorando/insere_despacho.php file. The application fails to properly sanitize or encode user-supplied input via the id_memorando GET parameter before reflecting it into the HTML source (likely inside a <script> block or an attribute). This allows unauthenticated attackers to inject arbitrary JavaScript or HTML into the context of the user's browser session. This vulnerability is fixed in 3.6.2.

WeGIA versions 3.4.12 and below contain an SQL Injection vulnerability in the /pet/profile_pet.php endpoint, specifically in the id_pet parameter, allowing attackers to execute arbitrary SQL commands, compromising the confidentiality, integrity, and availability of the database. This issue is fixed in version 3.5.0.

WeGIA versions 3.4.12 and below include an SQL Injection vulnerability in the /controle/control.php endpoint, specifically in the descricao parameter, allowing attackers to execute arbitrary SQL commands, compromising the confidentiality, integrity, and availability of the database. This issue is fixed in version 3.5.0.

WeGIA versions prior to 3.4.11 remain vulnerable to arbitrary file upload because the fix for CVE-2025-22133 was insufficient. The application only checks MIME types for Excel files at /html/socio/sistema/controller/controla_xlsx.php, which can be bypassed using Excel magic bytes in a PHP file, allowing webshell upload and remote code execution.
