CVE-2026-28411: WeGIA Vulnerable to Authentication Bypass via `extract($_REQUEST)`

WeGIA is a web manager for charitable institutions. Prior to version 3.6.5, an unsafe use of the `extract()` function on the `$_REQUEST` superglobal allows an unauthenticated attacker to overwrite local variables in multiple PHP scripts. This vulnerability can be leveraged to completely bypass authentication checks, allowing unauthorized access to administrative and protected areas of the WeGIA application. Version 3.6.5 fixes the issue.

Security readout for executives and security teams

Plain-English summary

WeGIA versions before 3.6.5 have a critical login bypass issue. A remote unauthenticated attacker could gain access to administrative or protected areas, putting sensitive institutional data and application integrity at risk. The vendor advisory states version 3.6.5 fixes the issue.

Executive priority

Treat as urgent for any deployed WeGIA instance. The vulnerability can bypass login without credentials and affects confidentiality, integrity, and availability. Prioritize internet-facing or shared-network deployments first.

Technical view

The issue is unsafe use of PHP extract() on $_REQUEST in multiple scripts. Request parameters can overwrite local variables used in authentication logic, enabling authentication bypass. The CVSS v3.1 score is 9.8 with network access, low complexity, no privileges, and no user interaction required.

Likely exposure

Organizations running WeGIA before version 3.6.5 are affected. Exposure is highest where WeGIA is reachable from the internet or untrusted networks. The sources do not identify specific hosted instances, default configurations, or compensating controls.

Exploitation context

The advisory describes unauthenticated remote authentication bypass to administrative and protected areas. The source bundle does not indicate known active exploitation, and the CVE is not listed as KEV in the provided data.

Researcher notes

Primary evidence is the vendor GitHub advisory and CVE record. The root cause is variable overwrite through extract($_REQUEST), mapped to CWE-288 and CWE-473. No exploit code, active exploitation evidence, or additional mitigations are provided in the supplied sources.

Mitigation direction

  • Upgrade WeGIA to version 3.6.5 or later.
  • Review the GitHub security advisory for vendor-specific guidance.
  • Restrict network access to WeGIA until upgraded, if business operations allow.
  • Monitor administrative account activity and protected-area access logs for anomalies.

Validation and detection

  • Inventory WeGIA deployments and record installed versions.
  • Confirm any instance below 3.6.5 is treated as vulnerable.
  • Verify upgraded systems report version 3.6.5 or later.
  • Review logs for unexpected protected-area access before remediation.
