CVE-2026-23729: Medium Vulnerability in WeGIA

WeGIA is a web manager for charitable institutions. Prior to version 3.6.2, an Open Redirect vulnerability was identified in the /WeGIA/controle/control.php endpoint of the WeGIA application. This vulnerability allows attackers to manipulate the nextPage parameter when combined with metodo=listarDescricao and nomeClasse=ProdutoControle. The application fails to validate or restrict the nextPage parameter, enabling attackers to redirect users to arbitrary external websites. This can be abused for phishing attacks, credential theft, malware distribution, and social engineering using the trusted WeGIA domain.

The vulnerability has a CVSS score of 4.8, classifying it as medium severity. Organizations that utilize WeGIA should prioritize patching this vulnerability, as it poses a significant risk to users and the integrity of the application.

This vulnerability is fixed in version 3.6.2, released on January 30, 2026.

Organizations should prioritize patching immediately.

The exploitation status indicates that no public exploit has been confirmed, and the vulnerability is not currently listed in the Known Exploited Vulnerabilities (KEV) catalog.

Given the potential for misuse, security teams must ensure that their deployment of WeGIA is up to date and configured correctly.

Vulnerability Details

The Open Redirect vulnerability allows attackers to redirect users without proper validation, which is classified under CWE-601. The vulnerability impacts all versions of WeGIA prior to 3.6.2.

Technical Analysis

The root cause of this vulnerability lies in the inadequate validation of user input for the nextPage parameter. The attack vector is network-based, with low complexity, requiring only low privileges and active user interaction.

The attack can compromise confidentiality and integrity, although it does not impact availability.

Risk & Impact Analysis

Risk to organizations includes the potential for phishing attacks, credential theft, and malware distribution. The vulnerability's medium severity indicates that it should be addressed in priority patch cycles.

The urgency of remediation is moderate, as the application can be exploited to redirect users to malicious external sites, leveraging the trusted WeGIA domain.

Exploitation Status

Affected Versions

All versions prior to vendor patch 3.6.2 are affected. Organizations should upgrade to this version to mitigate the vulnerability.

Mitigation & Remediation

To mitigate this vulnerability, organizations should update to WeGIA version 3.6.2. If an immediate upgrade is not feasible, consider implementing input validation for the nextPage parameter to restrict potential redirection.

For further assistance, organizations can benefit from penetration testing services to identify and remediate similar vulnerabilities.

Detection Guidance

Organizations should monitor logs for unusual redirection behaviors and user reports of phishing attempts. Implement network signatures to detect malicious redirects and ensure system changes are logged for review.

AppSecure Threat Intelligence Insight
