CVE-2026-55684 LabRedesCefetRJ CVE debrief

Who should care

Defenders responsible for WeGIA deployments, especially those used in sensitive or high-impact environments, should assess exposure and prioritize remediation to prevent potential data breaches or system disruptions. This includes verifying WeGIA version and deployment, testing for vulnerability, and applying version 3.8.6 or later. Additionally, defenders should review logs for suspicious SQL activity and consider implementing additional security controls

Why it matters

CVE-2026-55684 is a critical SQL injection vulnerability in WeGIA that allows for arbitrary SQL execution, potentially leading to sensitive data exposure or modification. Defenders responsible for WeGIA deployments should assess exposure and prioritize remediation to prevent potential data breaches or system disruptions.

• Potential exposure of sensitive data such as billing, member, employee, permission, and credential information
• Possible modification or deletion of sensitive data
• Potential disruption of critical systems or services
• Verification of WeGIA version and deployment to ensure remediation

Technical summary

The vulnerability exists in the /html/socio/sistema/cadastro_cobrancas_geracao.php endpoint of WeGIA, a web manager for charitable institutions. This endpoint accepts form-encoded POST data and interpolates user input into a raw INSERT statement without proper validation or quoting, allowing for arbitrary SQL execution. This could lead to sensitive data exposure or modification, including billing, member, employee, permission, and credential information. Defenders should assess exposure and prioritize remediation, especially in sensitive or high-impact environments, by verifying WeGIA version and deployment, testing for vulnerability, and applying version 3.8.6 or later.

Defensive priority

Defenders should prioritize immediate assessment and remediation of this vulnerability, especially if WeGIA is used in sensitive or high-impact environments.

Recommended defensive actions

• Assess exposure by reviewing WeGIA deployments and versions
• Verify if WeGIA instances are vulnerable by testing the /html/socio/sistema/cadastro_cobrancas_geracao.php endpoint
• Apply version 3.8.6 or later to remediate the vulnerability
• Monitor for suspicious SQL activity or anomalies in WeGIA logs
• Consider implementing additional security controls such as web application firewalls or SQL injection detection tools
